Knots to MPH Converter
Convert knots to miles per hour and back, instantly.
Compare nautical and statute speeds
Knots express nautical miles per hour and are standard in marine and aviation contexts. Miles per hour uses statute miles and is familiar for road travel. Since nautical and statute miles differ, the two hourly rates also differ. This converter applies the international nautical-mile relationship directly.
The default 20 knots converts to 23.0156 mph. In reverse, 60 mph converts to 52.1386 knots. The quick table supports rough comparison of vessel, aircraft, and wind speeds, while six significant figures preserve the underlying conversion for more specific values.
