A knot is a unit of speed that is equal to one nautical mile per hour, primarily used in maritime and aviation contexts. Unlike miles per hour or kilometers per hour, knots are specifically designed to measure speed over water or air, which makes them particularly useful for sailors and pilots.

How do you Convert Knots to MPH?

Converting knots to MPH can be done with a simple formula. The formula for doing this conversion is:

Understanding Your Results

Knots are commonly used in certain situations such as the sailing and boating realms as well as the plane and flying realm. This tool helps you easily convert a knot value to its equivalent MPH value. You can also convert it into a few different units of speed measurement if desired by choosing them from the dropdown menu.

How to Use the Knots to MPH Tool

Our knots to MPH converter is very simple to use. The steps involved are:

  1. Enter the speed in knots.

  2. Hit calculate and get the equivalent speed in MPH!

Example Calculation

Let's say you are on a fishing charter and overhear the captain say that the boat is traveling at 9 knots. You can use this tool to figure out how fast that is in miles per hour by entering 9 into the field and then hitting the calculate button. The result will be about 10.36 miles per hour.

Now let's say we are on a plane and it was a turbulent ride so we ask the captain how windy it was. They tell us the wind was about 40 knots. We can enter 40 into the knot field and hit calculate to get a result of 46.03 miles per hour.

Knots - Frequently Asked Questions

A single knot is equal to about 1.151 miles per hour.

10 knots is faster than 10 mph because 10 knots is equivalent to 11.51 mph.

25 knots is equal to about 28.77 mph.

Yes, airplane speeds are typically reported in knots rather than mph, but this is not always the case depending on the context and location.
