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? You might be surprised at the answer. Although 70 km/h is equivalent to 70 miles per hour, it is still very fast. 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 for the speed of aircrafts. One hundred kilometers per an hour equals 370 miles per an hour. Using a conversion factor, 70 km/h can be expressed in either metric or imperial units. The latter is preferred because it allows for more precise measurements.
