What is 70 km/h? You might have seen the speed limit on posters and billboards, but do you really know what 70 km/h actually means? The answer might surprise you. While 70 km/h is the equivalent of 70 miles per hour, this is still a very fast speed. It is important to understand that 70 km/h is twice the speed of 60 mph.
To convert 70 km/h to miles per hour, first convert the speed in kilometers. This is the standard unit for measuring automobile speed. The same formula applies to the speed of airplanes. One hundred kilometers per an hour equals 370 miles per an hour. 70 km/h can either be expressed in imperial or metric units by using a conversion factor. The latter is preferred because it allows for more precise measurements.
