Frequently Asked Questions

How do you convert knots to MPH?

To convert knots to miles per hour, multiply by 1.15078. The formula is: MPH = knots × 1.15078. For example, 10 knots = 10 × 1.15078 ≈ 11.51 MPH.

What is a knot and why is it used?

A knot is a unit of speed equal to one nautical mile per hour. It is primarily used in maritime and aviation contexts because it relates directly to navigation using latitude and longitude measurements on nautical charts.

How fast is 1 knot in MPH?

1 knot equals approximately 1.151 MPH. This means a boat traveling at 10 knots is moving about 11.5 MPH. The exact conversion factor is 1.150779, but 1.151 is commonly used for practical purposes.

Why do ships and planes use knots instead of MPH?

Knots are based on nautical miles, which are designed to work with latitude/longitude navigation. One nautical mile equals one minute of latitude, making navigation calculations simpler for pilots and sailors.

Can I convert MPH back to knots using this tool?

Yes, our knots to MPH converter allows bidirectional conversion. Enter any value in knots and you'll see the equivalent speed in MPH, or vice versa for easy comparison.
