How to Convert Knots to Miles Per Hour

conversion scale showing knots and equivalent miles per hour speed values

To convert a knot measurement to a mile per hour measurement, multiply the speed by the conversion ratio. One knot is equal to 1.150779 miles per hour, so use this simple formula to convert:

miles per hour = knots × 1.150779

The speed in miles per hour is equal to the knots multiplied by 1.150779.

For example, here's how to convert 5 knots to miles per hour using the formula above.
5 kn = (5 × 1.150779) = 5.753897 mph

Knots and miles per hour are both units used to measure speed. Keep reading to learn more about each unit of measure.

Knots

One knot is equal to a speed of one nautical mile per hour,[1] or one minute of latitude per hour.

Knots can be abbreviated as kn, and are also sometimes abbreviated as kt. For example, 1 knot can be written as 1 kn or 1 kt.

Miles Per Hour

Miles per hour are a measurement of speed expressing the distance travelled in miles in one hour.[2]

The mile per hour is a US customary and imperial unit of speed. Miles per hour can be abbreviated as mph, and are also sometimes abbreviated as mi/h or MPH. For example, 1 mile per hour can be written as 1 mph, 1 mi/h, or 1 MPH.

Miles per hour can be expressed using the formula:
vmph = dmithr

The velocity in miles per hour is equal to the distance in miles divided by time in hours.
