Multiply by 0.62 for a close mental estimate. The round metric limits map to awkward imperial ones — 100 km/h is 62.14 mph and 130 km/h is 80.78 mph — which is the reverse of the problem going the other way.

What a kilometer per hour and a mile 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.
