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

Is KM the same as hp?
Almost, but not quite. Metric horsepower - KM in Poland, PS in Germany - is 735.5 W, while imperial horsepower is 745.7 W. Vehicle papers across Europe quote the metric one, so a car listed at 150 KM is about 148 hp.
