But it's consistent and easy to use. How many drachms in a

How many electrons per second in an amp?

Is it more than 10?

Still SI units, but it's no simpler.

It amused me back in the 70s when Hertz became normal as the unit of
frequency. People bellyached like mad- they were quite prepared to
accept Hertz for radio waves, but not for sound- they insisted that
it had to be cycles per second, as it isn't electromagnetic, and
couldn't see that the unit makes no reference to the quantity being
measured. JS

But that's just a change of name not a change of units. 345.672Hz *is*
345.672 cycles per second.

Same as the Hectopascal. Why, though? I liked the millibar. I think it's the
French feeling left out again.
