About Speed Converter
Speed units are a length unit divided by a time unit, so they inherit the exact length definitions: 1 mph = 0.44704 m/s and 1 ft/s = 0.3048 m/s exactly.
Is it private?
Yes. Speed Converter runs entirely in your web browser. What you type is never sent to Nolo or anyone else, and the page cannot send it anywhere: its security policy only allows it to talk to nolotools.com, which has no place to receive data. Nothing is stored either: close the page and it is gone. How Nolo works.
Questions and answers
How do I convert km/h to mph?
Divide by 1.609344. For example 100 km/h รท 1.609344 = 62.14 mph.
How do I convert m/s to km/h?
Multiply by 3.6, because one hour has 3600 seconds and one km has 1000 metres.
What is a knot?
One nautical mile (1852 m) per hour, about 1.15 mph. It is used at sea and in aviation.
Does it convert pace (minutes per km)?
Not yet. This converter handles speed units (distance per time) only.
Is anything I type sent to a server?
No. The conversion runs in your browser with JavaScript and the page has no way to send your numbers anywhere. It also works offline once the page has loaded.
