What is a Knot?
A knot (kt) is a unit of speed commonly used in aviation and maritime industries. One knot equals one nautical mile per hour (1.852 km/h or about 1.151 mph). The term originates from old maritime speed measurements using knots tied in a rope.
Understanding Miles per Hour
Miles per hour (mph) is a standard unit of speed used in road transport and meteorology. It measures how many miles an object travels in one hour. This unit is widely used in the United States, the United Kingdom, and other countries.
Knots to Miles per Hour Conversion Formula
The conversion between knots and miles per hour follows a simple mathematical formula:
1 knot = 1.15078 mph
To convert knots to mph, multiply the speed in knots by 1.15078:
Speed (mph) = Speed (knots) × 1.15078
Example Calculation
If a boat is traveling at 20 knots, the speed in mph is:
20 knots × 1.15078 = 23.02 mph
This means the boat is moving at approximately 23 mph.
