Convert mile/hour to kilometer/hour

What is a mile/hour?

Speed units differ according to countries and their traditions and there are a lot of them. Thus, in the UK and the US, the mile/hour option is one of the most popular and common in everyday life. It shows the number of miles that are covered during one hour by the moving object.

One mile corresponds to 5280 feet or 1609.344 meters, and one hour is equal to 60 minutes or 3600 seconds. Therefore, 1 mph has the same meaning as 0.44704 m/s, 1.609344 km/h or 1.4667 fps.

The standard system utilizes meters/second, while common speed limits are usually given in kilometers/hour. Still, some English-specking countries, as well as Bahamas, Belize, Samoa and Caribbean regions give their preference to mi,h for this. In addition, this option is popular for a description of the speed of the ball during different sports events, including cricket, baseball and tennis.

What is a kilometer/hour?

Talking about speed, we always utilize some units. They are comfortable for understanding and we also require them for creating limits for public transport and vehicles. For instance, some countries have a rule that cars must not move faster than 16,7 meters/second or 60 kilometer/hour. The second number seems more convenient and understandable.

Therefore, km,h are often utilized as a non-standard speed unit. In this case, when someone says that an average walking speed is equal to 5 kph, it means that during 1 hour the distance of 5 km is covered by the pedestrian. For comparison, high-speed trains are moving with more than 500 km,h speed and airliners can have as much as 900 km/h.

To move back to the standard units of meter/second, one has just to divide the value by 3.6. Therefore, it is easy to switch between different speed units and use those that are suitable for the situation.
