Is my input uploaded to a server?
No. The conversion runs entirely in your browser, so nothing you enter leaves your machine.
How do I convert mph to km/h?
Multiply the mph value by 1.609344, since one mile is exactly 1.609344 kilometres. So 60 mph is about 96.56 km/h. This tool applies the exact factor.
What is a quick estimate?
Multiply by 1.6 (or add 60 percent). 50 mph is about 80 km/h. For an exact figure this tool uses the full factor.
Why do speed limits differ between countries?
Countries using miles post limits in mph, while metric countries use km/h — so a 60 mph limit is about 97 km/h. Converting helps when driving abroad.
Does it work for wind or running speeds too?
Yes. Any speed in mph converts the same way, whether it is a vehicle, wind, or pace figure.
