How to Convert Knots to Miles Per Hour

Speedometers are used in vehicles to measure speed

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.


One knot is equal to a speed of one nautical mile per hour, 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.

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.

Unit of Measurement Conversion Made Easy!

There are thousands of units of measure in use across the globe, and converting from one to another can be very difficult since each conversion requires a different formula to derive the result. Our unit of measurement conversion tools are meant to be dead easy. We break the mold of the typical dry and complicated experience. In addition to converting from one measurement to another, we provide the formula so you can see how the conversion is done, use it on you’re own calculator if you need to!

Understanding the Metric System

The metric system makes it relatively easy to convert from one metric unit to another metric unit. The metric system uses a base unit, think meters or grams, and a prefix such as kilo or milli. The prefixes differ from the base units by differing powers of 10. So to convert within the metric system it’s usually a matter of multiplying or dividing by one of the powers of 10.

Here is a list of some of the common metric prefixes:

  • “kilo” – 1,000x larger
  • “hecto” – 100x larger
  • “deca” – 10x larger
  • “deci” – 10x smaller
  • “centi” – 100x smaller
  • “milli” – 1,000x smaller

There is a helpful mnemonic for remembering the prefixes: “King Henry Died Until Drinking Chocolate Milk.”
The u in Until refers to the base unit.
