MPH to Knots Conversion: A Comprehensive Guide

Understanding the Conversion

MPH (miles per hour) and knots (kt) are both units of speed, but they are used in different contexts. MPH is typically used to measure the speed of land vehicles, while knots are used to measure the speed of watercraft and aircraft.

The conversion between MPH and knots is not exact due to different definitions of a nautical mile and a statute mile. A nautical mile is defined as the length of one minute of latitude along a meridian, which is approximately 1.15 statute miles. This difference means that 1 knot equals approximately 1.15 MPH.

Formula for Conversion

To convert MPH to knots, use the following formula:

Knots = MPH x 0.86897624

To convert knots to MPH, use the following formula:

MPH = Knots x 1.15077945
