The following extremely useful relation, specified in IEEE 1541-2002

Powers of 2^10 (1024) are very close to powers of 1000.

        2^0 =                      1 ~ 1000^0
[kibi] 2^10 =                   1024 ~ 1000^1
[mebi] 2^20 =                1048576 ~ 1000^2
[gibi] 2^30 =             1073741824 ~ 1000^3
[tebi] 2^40 =          1099511627776 ~ 1000^4
[pebi] 2^50 =       1125899906842624 ~ 1000^5
[exbi] 2^60 =    1152921504606846976 ~ 1000^6
