How to convert mph to km/h
miles per hour × 1.609344 = kilometers per hour
Speed limits are the common case, and they are set in round numbers in whichever system applies: 30 mph is 48.28 km/h, which is why the equivalent limit elsewhere is posted as 50 rather than as an exact conversion.

What a mile per hour and a kilometer per hour are
Both are units of speed, which is what makes them convertible at all: the converter above works by taking your value to a single reference unit for that family and back out again, so the figure it gives is the same one the table shows, carried to more digits. Nothing is sent anywhere to compute it — the arithmetic runs in this page, in your browser.
