How to convert mile per hour to knot
Mile per hour (mph) and Knot (kn) both measure speed. Whether you are studying, traveling, cooking, or working on a project, converting between them should be fast and accurate.
Looking for the opposite direction? See our dedicated knot to mile per hour converter — same formula reversed, with content written for that direction.
The standard relationship used on this page means that 1 mile per hour equals 0.868976 kn. Enter any number in the calculator — use the swap button to reverse the direction without leaving the page.
Converting 60 mph gives 52.138619 kn. This is a practical reference when switching between mile per hour and knot for driving abroad, aviation, running pace, and wind reports.

When you'll use this
- Converting a US-reported wind speed (mph) into knots for pilots, sailors, or marine forecasters
- Converting a US hurricane advisory's mph wind speeds into the knots used by international meteorological agencies and pilots
- Converting a boat's speed spec given in mph (common on some US boat listings) into knots for nautical comparison
- Converting a small aircraft's ground speed (sometimes displayed in mph on older instruments) into the knots used in aviation
- Checking a US weather report's mph wind gust figures against the knot-based thresholds used in marine and aviation warnings
Practical note
This page is especially useful around hurricane season: the US National Hurricane Center issues public advisories in mph, but pilots, sailors, and many international meteorological services work in knots — a hurricane reported at "115 mph" sustained winds converts to about 99.9 knots, just under the 100-knot threshold that has specific operational significance in aviation and marine safety planning. Boat shoppers use it too, since some US listings quote speed in mph while the rest of the boating world (and most marine electronics) display and expect knots.
Tips
- Divide mph by about 1.151 to get knots — useful when translating a US-style mph wind report into the knot-based warnings used by pilots and sailors.
- The US National Hurricane Center reports storm winds in mph for public consumption, but international agencies and pilots often use the same data expressed in knots — a hurricane with "100 mph" winds is about 86.9 knots.
- US boat listings occasionally state top speed in mph rather than the nautical-standard knots — converting to knots makes it easier to compare against other boats listed the standard way.
