Yes, they are.
Kilobites
2980
921.6 kilobytes.
There are 245,760 kilobytes (KB) in 240 megabytes (MB).
I am not exactly sure what 'MAB' or 'KAB' mean, but I would expect they mean something to the effect of 'Megabites' and 'Kilobites' in which case the 768KAB would convert to 76.8MAB which is significantly more.
There are 1024 megabites in 1 gigabite. 20 gigabites has 20,480 megabites.
No. Kilobytes are very small. I'm not sure how many are in Gigabytes, but I can answer your question. Kilobytes are smaller than both Gigabytes and Megabytes.
8
512 kb is 512 kilobites.
A KB is smaller than a MB because there are 1000 kilobites (KB) in a megabite (MB)
2,000,000 kilobites are in 2gb.
how much time does it take to use 250 megabites when the computer is in use?
It is 1024 KB in 1Mb.
