FAQs

How many km/h is 100 mph?
100 miles per hour equals 160.9344 kilometers per hour. One mile is 1,609.344 meters, so multiply mph by 1.609344 to get km/h.
What is the difference between knots and km/h?
A knot is one nautical mile per hour and a nautical mile is 1,852 meters. So 1 knot equals exactly 1.852 km/h. Knots are used in aviation and at sea.
How do I convert m/s to km/h?
Multiply meters per second by 3.6. For example, 10 m/s times 3.6 equals 36 km/h. To go the other way, divide km/h by 3.6.
Are the conversions exact?
The unit factors are based on exact definitions (one mile is 1,609.344 meters, one foot is 0.3048 meters, one nautical mile is 1,852 meters). Results are rounded to a sensible number of digits to avoid floating point noise.
