Info about "Miles per hour"

The unit of length known as a "mile" and it should not be confused with the nautical mile and very commonly used in the Anglo-American countries. Therefore, the metric system is defined in miles (instead of kilometers) per time unit. For example, if a vehicle travels at a speed of 100 miles per hour (100 mph), it will move around 160 km per hour in the metric system.

The units are defined as follows: An object moving at 1 "mph" per hour will cover a distance of one mile. Therefore, 1 mile is equivalent to 1.609344 kilometers.

Info about "Knot"

Definition: An object that moves with a knot for one hour will cover a distance of one nautical mile. Therefore 1 nautical mile is equivalent to 1,852 meters. A knot refers to the speed of one nautical mile per hour.

The following rule is an easy way to remember when converting knots into km/h: "Multiply by two, and minus 10%". For example, a ship travelling at 20 knots will have a speed around 40-4=36 km/h (exactly 37.04 km/h).
