Paste one conversion per line, written the way you would say it: "5 km to mi". Handy for a column copied out of a spreadsheet.

Questions people actually ask

How do RPM and hertz relate?
One revolution per second is one hertz, so 60 RPM is 1 Hz and a 3000 RPM engine is turning at 50 Hz. Radians per second is the same rotation measured in angle: one turn is 2π radians.
