Conversion Formulas

Feel free to convert knots to miles per hour (knots to mph) and miles per hour to knots (mph to knots) using our conversion chart and conversion calculator and learn the relationship between these two units.

Conversion of knots to miles per hour (knots to mph) and miles per hour to knots (mph to knots) is easy since both units measure speed.

Obviously, the knots and miles per hour are not units of the SI system of units, but they are still used very often.

Miles and nautical miles are used to measure length, while miles per hour (mph) and nautical miles per hour (knots) measure speed.

Their relationships are as follows:

1 nautical mile (nm) = 1852 m → 1 meter = 1/1852 nm

1 knot = 1852 m / 3600 s = 0.5144 m/s

Similarly:

1 mile = 1609.34 m

1 mph = 1609.34 m / 3600 s = 0.44703 m/s

Thus, if we want to convert knots to mph and mph to knots, we can write:

1 mph = 1609.34 m / 1852 m = 0.868974 knots

1 knot = 1853 m / 1609.34 m = 1.150782 mph

These last two formulas allow us to convert mph to knots and knots to mph easily.
