When in top, typing capital "E" cycles through different memory units (kb, mb, gb etc) in the total memory info:
While lower-case "e" does the same individual process lines:
From the manpage:
2c. MEMORY Usage
This portion consists of two lines which may express values in kibibytes
(KiB) through exbibytes (EiB) depending on the scaling factor enforced

There is a command-line option which does that:
-M : Detect memory units
Show memory units (k/M/G) and display floating point values in the
memory summary.
So it is sufficient to run top like that:
top -M
If -M does not work you can press E while already in top.
From man top (procps-ng version 3.3.9):
E :Extend-Memory-Scale in Summary Area
With this command you can cycle through the available summary area memory scaling which ranges from KiB (kibibytes or 1,024 bytes) through EiB (exbibytes or 1,152,921,504,606,846,976 bytes).
If you see a '+' between a displayed number and the following label, it means that top was forced to truncate some portion of that number. By raising the scaling factor, such truncation can be avoided.

You can also use htop. It's much cooler than top.
If you are using Debian or one of its derivatives, then you can install it using sudo apt-get install htop.

top -M doesn't work on any of the Fedora, Debian or Ubuntu distros to my knowledge. I just tried it and it's not in the procps-ng package that provides top. There are many implementations of top so one needs to pay special attention to which they use.
In general it's best to use free with switching to get the amount of memory free on Linux.
procps vs. procps-ng
You might of noticed that on CentOS 5 & 6 as well as RHEL 5 & 6 that top -M appears to work. This is because those distros ship with the original version of procps. The project was forked and there is now another project procps-ng.
Some of the details as to why there was fork, from the Fedora Project's page.
excerpt
Old (legacy) procps tools had no updates for several years and that led to a massive code split caused by a local-only application of distribution specific patches, which were not merged upstream. The project became hardly maintainable since some of the newly written patches were incompatible with sources maintained by other distributors. A similar incompatibility could be noticed in the applications behavior and their command line switches. This inevitable update can be understood as an effort to unify the procps tools across all Linux distributions.
So to be clear, the forked project, procps-ng is what Debian, Fedora, Ubuntu, and other distros are using, the legacy project, which does support top -M is still in use of several of the longer term releases that don't keep up with the latest and greatest.
NOTE: I downloaded the latest version of procps-ng, "procps-ng version 3.3.9.1-14ef" and it too was lacking the -M switch.
$ ./top/top -version
procps-ng version 3.3.9.1-14ef
Usage:
lt-top -hv | -bcHiOSs -d secs -n max -u|U user -p pid(s) -o field -w [cols]
free
In running free with switches you can see the most likely reason as to why the lack of units feature is missing from procps-ng's implementation of top.
$ free -m
total used free shared buffers cached
Mem: 7782 6506 1276 0 504 1726
-/+ buffers/cache: 4274 3507
Swap: 7823 1429 6394
[saml@greeneggs ~]$ free -k
total used free shared buffers cached
Mem: 7969492 6663180 1306312 0 516948 1764780
-/+ buffers/cache: 4381452 3588040
Swap: 8011772 1463456 6548316
Rounding becomes problematic, so I believe, procps's implementation avoids the issue by not offering the ability.
htop
Does an OK job of showing aggregate memory usage.
atop
In my opinion a better tool for looking at memory.
nmon
Another useful tool is nmon for looking at system performance.

@AnthonyAnanich - I researched this a bit more. CentOS 5.4's top version "procps version 3.2.8" has the-Mswitch, CentOS 5.8, also has this switch, "procps version 3.2.7". However Fedora 19 has "procps-ng version 3.3.8" which doesn't support the-Mswitch.

@AnthonyAnanich - NP. You should consider picking one if you feel that it answers your Q 100%. Accepting an A is important since it signals to the rest of the community that passes by your Q that you as the OP felt this A answered or solved your particular issues. If other A's are outstanding they'll get UV'd as well. Not accepting one, is basically a signal that you as the OP still feel your Q hasn't bee sufficiently answered. The accepted A also gets positioned as the 1st A when ppl see your Q in the future.

So the quick answer : depending on your linux distro, try either :
top -M
OR, after starting top, type capital E (then W to write the config).
One of those should work for nearly everybody (except Solaris, of course, where you'd be lucky to have top at all).
bonus tip : every time you start a top instance on a new install, type ExyzW to save colours and highlighting and units - what a relief!

On RHEL7
top
shift + e or CspsLK ON. You need " E " capital alphabet.
You will get in MiB, Gib, TiB, PiB, EiB. All these you can access.
And also you can you htop command which should be downlaoded and installed on rpm base system.
Thank you.

There is a command-line option which does that:
-M : Detect memory units
Show memory units (k/M/G) and display floating point values in the
memory summary.
So it is sufficient to run top like that:
top -M
If -M does not work you can press E while already in top.
From man top (procps-ng version 3.3.9):
E :Extend-Memory-Scale in Summary Area
With this command you can cycle through the available summary area memory scaling which ranges from KiB (kibibytes or 1,024 bytes) through EiB (exbibytes or 1,152,921,504,606,846,976 bytes).
If you see a '+' between a displayed number and the following label, it means that top was forced to truncate some portion of that number. By raising the scaling factor, such truncation can be avoided.

You can also use htop. It's much cooler than top.
If you are using Debian or one of its derivatives, then you can install it using sudo apt-get install htop.

top -M doesn't work on any of the Fedora, Debian or Ubuntu distros to my knowledge. I just tried it and it's not in the procps-ng package that provides top. There are many implementations of top so one needs to pay special attention to which they use.
In general it's best to use free with switching to get the amount of memory free on Linux.
procps vs. procps-ng
You might of noticed that on CentOS 5 & 6 as well as RHEL 5 & 6 that top -M appears to work. This is because those distros ship with the original version of procps. The project was forked and there is now another project procps-ng.
Some of the details as to why there was fork, from the Fedora Project's page.
excerpt
Old (legacy) procps tools had no updates for several years and that led to a massive code split caused by a local-only application of distribution specific patches, which were not merged upstream. The project became hardly maintainable since some of the newly written patches were incompatible with sources maintained by other distributors. A similar incompatibility could be noticed in the applications behavior and their command line switches. This inevitable update can be understood as an effort to unify the procps tools across all Linux distributions.
So to be clear, the forked project, procps-ng is what Debian, Fedora, Ubuntu, and other distros are using, the legacy project, which does support top -M is still in use of several of the longer term releases that don't keep up with the latest and greatest.
NOTE: I downloaded the latest version of procps-ng, "procps-ng version 3.3.9.1-14ef" and it too was lacking the -M switch.
$ ./top/top -version
procps-ng version 3.3.9.1-14ef
Usage:
lt-top -hv | -bcHiOSs -d secs -n max -u|U user -p pid(s) -o field -w [cols]
free
In running free with switches you can see the most likely reason as to why the lack of units feature is missing from procps-ng's implementation of top.
$ free -m

Rounding becomes problematic, so I believe, procps's implementation avoids the issue by not offering the ability.
htop
Does an OK job of showing aggregate memory usage.
atop
In my opinion a better tool for looking at memory.

Another useful tool is nmon for looking at system performance.

@AnthonyAnanich - NP. You should consider picking one if you feel that it answers your Q 100%. Accepting an A is important since it signals to the rest of the community that passes by your Q that you as the OP felt this A answered or solved your particular issues. If other A's are outstanding they'll get UV'd as well. Not accepting one, is basically a signal that you as the OP still feel your Q hasn't bee sufficiently answered. The accepted A also gets positioned as the 1st A when ppl see your Q in the future.

top -M doesn't work on any of the Fedora, Debian or Ubuntu distros to my knowledge. I just tried it and it's not in the procps-ng package that provides top. There are many implementations of top so one needs to pay special attention to which they use.
In general it's best to use free with switching to get the amount of memory free on Linux.
procps vs. procps-ng
You might of noticed that on CentOS 5 & 6 as well as RHEL 5 & 6 that top -M appears to work. This is because those distros ship with the original version of procps. The project was forked and there is now another project procps-ng.
Some of the details as to why there was fork, from the Fedora Project's page.
excerpt
Old (legacy) procps tools had no updates for several years and that led to a massive code split caused by a local-only application of distribution specific patches, which were not merged upstream. The project became hardly maintainable since some of the newly written patches were incompatible with sources maintained by other distributors. A similar incompatibility could be noticed in the applications behavior and their command line switches. This inevitable update can be understood as an effort to unify the procps tools across all Linux distributions.
So to be clear, the forked project, procps-ng is what Debian, Fedora, Ubuntu, and other distros are using, the legacy project, which does support top -M is still in use of several of the longer term releases that don't keep up with the latest and greatest.
NOTE: I downloaded the latest version of procps-ng, "procps-ng version 3.3.9.1-14ef" and it too was lacking the -M switch.
$ ./top/top -version
procps-ng version 3.3.9.1-14ef
Usage:
lt-top -hv | -bcHiOSs -d secs -n max -u|U user -p pid(s) -o field -w [cols]
free
In running free with switches you can see the most likely reason as to why the lack of units feature is missing from procps-ng's implementation of top.
$ free -m
total used free shared buffers cached
Mem: 7782 6506 1276 0 504 1726
-/+ buffers/cache: 4274 3507

Swap: 8011772 1463456 6548316
Rounding becomes problematic, so I believe, procps's implementation avoids the issue by not offering the ability.
htop
Does an OK job of showing aggregate memory usage.
atop
In my opinion a better tool for looking at memory.
nmon
Another useful tool is nmon for looking at system performance.

@AnthonyAnanich - I researched this a bit more. CentOS 5.4's top version "procps version 3.2.8" has the-Mswitch, CentOS 5.8, also has this switch, "procps version 3.2.7". However Fedora 19 has "procps-ng version 3.3.8" which doesn't support the-Mswitch.

@AnthonyAnanich - NP. You should consider picking one if you feel that it answers your Q 100%. Accepting an A is important since it signals to the rest of the community that passes by your Q that you as the OP felt this A answered or solved your particular issues. If other A's are outstanding they'll get UV'd as well. Not accepting one, is basically a signal that you as the OP still feel your Q hasn't bee sufficiently answered. The accepted A also gets positioned as the 1st A when ppl see your Q in the future.

So the quick answer : depending on your linux distro, try either :
top -M
OR, after starting top, type capital E (then W to write the config).
One of those should work for nearly everybody (except Solaris, of course, where you'd be lucky to have top at all).
bonus tip : every time you start a top instance on a new install, type ExyzW to save colours and highlighting and units - what a relief!

On RHEL7
top
shift + e or CspsLK ON. You need " E " capital alphabet.
You will get in MiB, Gib, TiB, PiB, EiB. All these you can access.
And also you can you htop command which should be downlaoded and installed on rpm base system.
Thank you.

Apparently, some posts say that in Redhat Linux you can do someting like
top -Mto display the usage in MB. If you only want to monitor the memory usage, you can use rather usehtop. Not sure of any other option.– Barun
