A:
I guess you could say that any calculation uses ideas like logs
indirectly, but here's how I do it without using any log tables or
calculators.
You know 2^10=1024. That's about 10^3.
So 2^30 =1024^3, or about 10^9.

This number crops up all the time in computer applications; It's
very close to one billion, as above, and so one Gigabyte is really 2^30
bytes. -- Tom
