No, 10MB or 100MB, etc. was measured using powers of 2. It's not true that it was always based 10.
It made a big stir when they reached GB range and changed to powers of 10. I remember it.

The label of this drive gives us CHS figures for three different models:
cyl * h * s * B
127MB = 919 * 16 * 17 * 512 = 127,983,616B (124MiB)
170MB = 1011 * 15 * 22 * 512 = 170,818,560B (162MiB)
340MB = 1011 * 15 * 44 * 512 = 341,637,120B (325MiB)
For some reason everyone remembers it, but no-one's been able to show me.
