The easiest way is to remember that 1 Km = .6 miles. This can be translated into speeds pretty easily with simple multiplication or division.
For example, your 60 kmh would equal 36 mph.
60 kph x .6 = 36 mph
Even simpler: 10 kmh = 6 mph (10 kmh x .6 = 6 mph)
Conversely, 20 mph would equal 33.3 kmh, which is done by dividing. 20 mph / .6 = 33.3 kph
or a simpler one: 6 mph = 10 kmh (6 mph / .6 = 10 kph)
It all revolves around the .6 .
Hopefully this cleared things up for you. :cool:
