What This Tool Does
This tool converts a speed in miles per hour (mph) to kilometres per hour (km/h) using the exact factor: 1 mph = 1.609344 km/h. It is useful when a car review, speed limit sign, treadmill display or sports statistic is quoted in mph and you want to compare it with the km/h numbers you see on an Indian speedometer.
How to Use It
- Type your value into the field (the tool is pre-set for this conversion).

A car advertised with a 155 mph electronically limited top speed tops out at about 249 km/h. A 70 mph US interstate limit works out to roughly 113 km/h, and a 12 mph treadmill setting is around 19.3 km/h.
