    I've always been confused when working on old equipment that uses cycle per second, especially when all my test equipment is in Hertz. I found this handy chart that I've printed and put on the wall by the bench. Now no calculators or computers needed to do the conversion, just look up at the handy chart.

    Nothing new there.

    What I did is set up a conversion on my scientific calculator. Enter one frequency expressed either way, and it automatically multiplies by 1 and displays the conversion. Works perfectly.

    No conversion necessary.

    One cps = one hertz

    You have test equipment in Hertz?

    Not MHz or kHz? Just the 'H'?

    We had a big Harley rally recently and so many bikes were passing by, I was able to express them in Motorhertz.

    The road I live on is usually part of some Harley run or another all year. Every Saturday during riding time (it still is, believe it or not) plus all the other bike events seem to be held right in front of my house.

    Just a guess, but I think the standard rate would be about 2 motorhertz. That would be a pass a second with two bikes per lane. I think that's reasonable in a 35 mph school zone between taverns.

    I have the same thing here. In fact, everywhere I've lived within 50 miles of here has been that way. Come to think of it all the (non-subdivision) streets have this problem around here.

    Obviously the results of a government-funded study.
