Answers: 1 MB = 1024 KB
So, 81920 KB = 81920 / 1024 MB = 80 MB

81.92
Edit: Thanks adjectives, I've be enlightened too, other took it as moving dec point 3 places. Just go to show you're never too hoary to revise! ;-)
80 MB
81920 / 1024
1MB = 1024KB
roughly: it is 81.92mb
exactly.. 80mb
80! kb, mb,gb etc are other measured within divisions of 1,024 fairly than 1000.
if you don't beleive me here are some examples:
Old computers
Commodore 64k = (1024 / 16)
BBC Micro 32k = (1024 /32)
C16 = (1024 /64)
Modern computers
512mb = (1024 /2)
256gb = (1024 /4)
Other
Standard phone Cameras=2mpix (1024 /512)
Standard Dial up Broadband -512 kbps (1024 / 2)
They purely round it up.
1024 is the sleight of hand number.
