Knots to Mph Formula

A knot is defined as the speed equal of one nautical mile per hour. A nautical mile (nmi) is 1852 meters (6076.11548556 ft), whereas an international mile (mi) is 1609.344 meters (5280 ft); the term international mile stands for land miles also known as statute miles.

to convert knots to mph we have to multiply the speed in knots by α = 1852 / 1609.344. The formula is [mph] = α x [kts] . Using the value 1.15078 for α we get the

approximation [mph] = [kts] x 1.15078.

In other words, 1 knot to mph ~ 1.15 mph. One knot equals approximately 1.15078 miles per hour. The speed in mph is always about 15 percent more than the speed in knots.

In other common units of speed one knot equals approximately 1.68781 foot per second or 0.514444 meter per second, and is exactly 1.852 kilometers per hour.
