Worked examples
Converting 5 megabytes
Multiply 5 by 0.95367432. That gives 4.7684 mebibytes. A quick sanity check: one megabyte is smaller than one mebibyte, so the number should get smaller — and it does.
Converting 72 megabytes
72 × 0.95367432 = 68.6646 mebibytes. Working backwards, 68.6646 ÷ 0.95367432 returns 72 megabytes, which confirms the factor is applied the right way round.
