Speed Units
The speed units in this speed converter tool are the most common speed units from the metric and the Imperial measurement systems. To convert all speed units, please check all speed conversions page.
What is Miles per Hour?
Miles per hour is an Imperial and United States Customary speed unit to express the number of miles covered in one hour. It is mostly used in the United States and the United Kingdom. It is symbolized as mph or mi/h.
How to convert mph to km/h?
1 Mile per hour (mph) is equal to 1.60934 kilometers per hour (km/h). To convert mph to km/h multiply the mph value by 1.60934.
To convert between mph and kph and access the tables, please check mph to kph page.
How to convert mph to m/s?
As there are 1609.344 meters in a mile and 3600 seconds in an hour, divide 1609.344 by 3600, that makes 0.44704 meter per second equals to 1 mile per hour.
For example, to find out how many meters per second is 25 miles per hour, divide (25 * 1609.344) by 3600, that makes 11.176 meters per second equals to 25 miles per hour.
Here is the speed conversion factors list from miles per hour to other common speed units:
1 Mile per Hour (mph) =
- 1.60934 kilometers per hour
- 0.447039 meters per second
- 1.46667 feet per second
- 0.868976 knot
For speed conversion from miles per hour to other speed units, multiply the mile per hour value with the conversion factors.
What is Kilometers per Hour?
Kilometers per hour is a metric system speed unit to express the number of kilometers covered in one hour. It is used globally except the United States and the United Kingdom. It is symbolized as kph or km/h.
How to convert km/h to mph?
1 Kilometer per hour (kph) is equal to 0.621373 miles per hour (mph). To convert kilometers per hour to mph multiply the kilometer per hour value by 0.621373 or divide by by 1.60934.
How to convert km/h to m/s?
As there are 1000 meters in a kilometer and 3600 seconds in an hour, divide 1000 by 3600, that makes 0.277778 m/s equals to 1 km/h.
For example, to find out how many meters per second is 5 kilometers per hour, divide 5000 by 3600, that makes 1.38889 m/s is 5 km/h.
Here is the speed conversion factors list from kilometers per hour to other common speed units:
1 Kilometer per Hour (km/h) =
- 0.621373 mile per hour
- 0.277778 meters per second
- 0.911344 feet per second
- 0.539957 knot
For speed conversion from kilometers per hour to other speed units, multiply the kilometers per hour value with the conversion factors.
What is Meters per Second?
Meters per second is a metric system speed unit to express the number of meters covered in one second. It is symbolized as mps or m/s.
How to convert m/s to ft/s?
1 Meter per second (m/s) is equal to 3.28084 feet per second (ft/s). To convert meters per second to feet per second, multiply the meters per second value by 3.28084.
How to convert m/s to km/h?
As there are 1000 meters in a kilometer and 3600 seconds in an hour, divide 3600 by 1000, that makes 3.6 km/h is equal to 1 m/s.
Here is the speed conversion factors list from meters per second to other common speed units:
1 Meter per Second (m/s) =
- 2.23694 miles per hour
- 3.6 kilometers per hour
- 3.28084 feet per second
- 1.94384 knot
For speed conversion from meters per seond to other speed units, multiply the meters per second value with the conversion factors.
What is Feet per Second?
Feet per second is an Imperial and US Customary speed unit to express the number of feet covered in one second. It is symbolized as fps or ft/s.
How to convert ft/s to m/s?
1 Foot per second (ft/s) is equal to 0.3048 meters per second (m/s). To convert feet per second to meters per second, multiply the feet per second value by 0.3048 or divide by 3.28084.
How to convert ft/s to mph?
As there are 5280 feet in a mile and 3600 seconds in an hour, divide 3600 by 5280, that makes 0.681817 mph is equal to 1 ft/s.
Here is the speed conversion factors list from feet per second to other common speed units:
1 Foot per Second (ft/s) =
- 0.681817 mile per hour
- 1.09728 kilometers per hour
- 0.3048 meters per second
- 0.592484 knot
For speed conversion from feet per second to other speed units, multiply the feet per second value with the conversion factors.
What is a Knot?
The knot is a speed unit and mostly used for measuring the vessel speed. 1 knot is equal to one nautical mile (1.852 km/h) per hour. It is symbolized as kn.
How to convert knot to mph?
1 Knot (kn) is equal to 1.15078 miles per hour (mph). To convert knots to miles per hour, multiply the knot value by 1.15078.
For example, to find out how many miles per hour (mph) is 160 knots, multiply 160 by 1.15078, that makes 184.125 miles per hour.
How to convert knot to km/h?
1 Knot (kn) is equal to 1.852 kilometers per hour (km/h). To convert knots to kilometers per hour, multiply the knot value by 1.852.
For example, to find out how many kilometers per hour (km/h) is 160 knots, multiply 160 by 1.852, that makes 296.32 kilometers per hour.
Here is the speed conversion factors list from knots to other common speed units:
1 Knot (kn) =
- 1.15078 miles per hour
- 1.852 kilometers per hour
- 0.514446 meters per second
- 1.68781 feet per second
For speed conversion from knots to other speed units, multiply the knot value with the conversion factors.
