File Size Calculator

Hi all, I'm trying to writing a script that will allow a user to enter a
number and that number will be converted into KB,MB or GB depending on the
size of the number. Can someone point me in the right direction?

Example:
user enter: 59443
Script will output: 58M

What have you got so far? Where are you stuck? Getting user input
(where from)? Working out which order of magnitude the number is?
Converting between kilo and mega et al? Showing the output?

Show us some code.

I know this isn't getting into the spirit of things, but have you
considered simply using the `units` program?

% units
500 units, 54 prefixes
You have: 59443 bytes
You want: megabytes
* 0.056689262
/ 17.640025
You have: 59443 bytes
You want: kilobytes
* 59.443
/ 0.016822839
You have: ^C
% units bytes kilobytes
* 0.001
/ 1000

% units bytes megabytes
* 9.5367432e-07
/ 1048576

The nice thing about `units` -- in this context -- is that it lets the
user pick the conversion units they want to work with, and also gives
hints for converting both to & from the alternate measurement scale.

Of course, working this into a larger program that does other things
might be annoying -- in which case your way is better -- but if all you
want is the conversions, this is a solved problem :-)
