Frequently asked questions
- What is 26.2 miles in kilometres?
- 42.165 km. The marathon is defined as 42.195 km, which is 26.2188 miles, so 26.2 is a rounding of the distance rather than the definition.
- Does this work for miles per hour?
- Yes. Speed is distance over time, and the time unit does not change, so 60 mph is 96.56 km/h by the same factor.

- No. The conversion runs inside your browser. Nothing you type is uploaded, stored or logged, and the page keeps working with the network disconnected.
