Estimating Bits and Bytes
Via Richard Feynman's Computing Heuristics lecture on Youtube
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
