Common questions
How many miles per hour is 100 km/h?
100 km/h is 62.137119 mph. The conversion is exact rather than approximate: a mile is 63,360 inches, and an inch is defined as exactly 2.54 cm.
What is a knot, and why is it not a mile per hour?
A knot is one nautical mile per hour. A nautical mile is exactly 1,852 metres — longer than a land mile — so one knot is about 1.151 mph.
How do I convert metres per second to km/h?
Multiply by 3.6. A speed of one metre per second covers 3,600 metres in an hour, which is 3.6 kilometres. Divide by 3.6 to go back the other way.
