## How to Convert Miles per Hour to Knots

To convert a measurement in miles per hour to a measurement in knots, multiply the speed by the following conversion ratio: 0.868976 knots/mile per hour.

Since one mile per hour is equal to 0.868976 knots, you can use this simple formula to convert:

knots = miles per hour × 0.868976

The speed in knots is equal to the speed in miles per hour multiplied by 0.868976.

**For example,**here's how to convert 5 miles per hour to knots using the formula above.

Miles per hour and knots are both units used to measure speed. Calculate speed in miles per hour or knots using our speed calculator or keep reading to learn more about each unit of measure.

## What Are Miles per Hour?

Miles per hour are a measurement of speed expressing the distance traveled in miles in one hour.^{[1]}

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.
