## How to Convert Knots to Miles Per Hour

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:

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.

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:

v_{mph} = d_{mi}t_{hr}

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