Here is our mph to knots conversion calculator which will help you convert between the two different speeds in miles per hour and knots.
The converter will also show you the formula you need to convert between units.
How It Works...
Step 1) Type in the speed.

Step 3) Click the Convert button and the answer will be displayed.
A knot is a unit of speed. It is equal to 1 nautical mile per hour.
A nautical mile is used to measure distances at sea. It is equal to 1 minute of the Earth's latitude.
It is slightly longer than a 'normal' mile.
1 nautical mile = 1.15078 miles.
So 1 knot = 1.15078 miles per hour.
How to convert mph to knots
To convert an amount from miles per hour to knots, you just need to divide the amount by 1.151 (to 3dp).
