Both unfortunately. The prefixes for the decimal system (table below) use a power of 10 factor. Prefix Symbol Factor kilo k 1 000 (10^3) mega M 1 000 000 (10^6) giga G 1 000 000 000 (10^9) tera T 1 000 000 000 000 (10^12) peta P 1 000 000 000 000 000 (10^15) Other prefixes have been standardized recently (1998) for the binary units. Prefix Symbol Factor kibi Ki 1 024 (2^10) mebi Mi 1 048 576 (2^20) gibi Gi 1 073 741 824 (2^30) tebi Ti 1 099 511 627 776 (2^40) pebi Pi 1 125 899 906 841 504 (2^50) Unfortunately, the decimal prefixes have been used with the meaning of the binary prefixes. Most of (*most of*, not *all*) the time the decimal prefix is a binary prefix in the context of memory (RAM, HD, ...), and a true decimal prefix in the context of bandwidth. It would be nice to make use of the binary prefixes in the mjpegtools...
