Easy Way to Convert knots to mph

One knot equals 1.15078 miles per hour. To convert knots to mph, simply multiply the number of knots by 1.15078. For example:

  • 10 knots = 11.51 mph
  • 20 knots = 23.02 mph
  • 30 knots = 34.52 mph

Knots to mph formula

The mathematical formula for converting knots to mph is: Miles per hour (mph) = Knots × 1.15078

Why is Knot Used Instead of MPH?

Knots remain the standard unit of speed measurement in maritime and aviation contexts for several practical reasons:

  1. Global Navigation: Knots directly relate to nautical miles, which are based on the Earth’s circumference. One nautical mile equals one minute of arc along a meridian, making navigation calculations more intuitive.
  2. International Standard: The maritime industry worldwide uses knots, ensuring clear communication between vessels and ports from different countries.
  3. Weather Patterns: Wind speeds and ocean currents are traditionally measured in knots, making it easier for sailors and pilots to correlate their speed with weather conditions.
