How does the speed converter work?

All speed units are stored relative to meters per second. The calculator converts your value to m/s, then to the target unit, ensuring exact conversion between miles per hour, kilometers per hour, knots, and meters per second.

How do I convert mph to km/h?

Multiply miles per hour by 1.609344 to get kilometers per hour. For example, 60 mph equals about 96.6 km/h. This converter works in both directions instantly.

A knot is a nautical speed unit equal to one nautical mile per hour, or about 1.852 km/h. It is used in aviation, sailing, and maritime navigation.

How many meters per second is 100 km/h?

Divide km/h by 3.6: 100 km/h is about 27.8 m/s. This conversion is common in physics and engineering problems.

Which speed unit should I use?

It depends on context. Miles per hour are common in the US and UK; km/h elsewhere; knots for marine and aviation; m/s for science. The converter supports all four.
