Kilometres per hour to Miles per hour Conversion

The mile per hour, commonly abbreviated as mph, is a unit of speed originating from the British imperial system and widely used in the United States and the United Kingdom. It’s fascinating to know that the concept of mph has historical significance dating back to the invention of the first automobiles in the late 19th century. The iconic cars of the 1920s, often called “classic cars,” were among the first to publicly advertise their capabilities in mph, including models like the Ford Model T, which had a top speed of about 45 mph.

Interestingly, mph is still the primary speed measurement unit for most road signage in countries such as the US and the UK, even while the rest of the world predominantly uses kilometers per hour (kph). The land-speed record attempts, including those made with the supersonic car “ThrustSSC,” which achieved an astonishing 763 mph in 1997, also emphasize the significance of this unit in measuring extreme speeds.
