How to Convert Knots to Miles per Hour

To convert a measurement in knots to a measurement in miles per hour, multiply the speed by the following conversion ratio: 1.150779 miles per hour/knot.

Since one knot is equal to 1.150779 miles per hour, you can use this simple formula to convert:

miles per hour = knots × 1.150779

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

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

What Are Miles per Hour?

Miles per hour are a measurement of speed expressing the distance traveled 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 = dmi / thr

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