You can use the command line option E to specify the memory scaling, for example in gigabytes:

$ top -E g 

From man top:

-E :Extend-Memory-Scaling as: -E k | m | g | t | p | e Instructs top to force summary area memory to be scaled as: k - kibibytes m - mebibytes g - gibibytes t - tebibytes p - pebibytes e - exbibytes Later this can be changed with the `E' command toggle. 

The -e option can be used with the same options to change the values in the task list.
