Convert a speed between miles per hour, kilometers per hour, meters per second, and knots.

LiveConverted value
96.56 km/h
The formula
Result = Value x (m/s per "From" unit) / (m/s per "To" unit)
Example
60 mph converts to about 96.56 km/h, or 26.82 m/s, or 52.14 knots.
Step-by-step guide
- Enter the value you want to convert.
- Choose the "from" and "to" units.
- Read the converted result.
Common mistakes
Confusing knots with mph - a knot (nautical mile per hour) is about 15% faster than a mph, a common error in aviation and marine contexts.
Mixing up m/s with km/h without converting - m/s numbers look much smaller than km/h for the same actual speed, since there are 3,600 seconds in an hour.
Frequently asked questions
Why do ships and planes use knots?
A knot is based on the nautical mile, which relates directly to degrees of latitude - a historically convenient unit for marine and aviation navigation that remains standard today.
What's a quick way to estimate mph from km/h?
Multiply km/h by about 0.62 for a rough mph estimate, or divide by 1.6. For an exact figure, use the calculator above.
Is this useful for wind speed too?
Yes - the same unit conversions apply whether you're converting vehicle speed, wind speed, or any other rate expressed as distance per time.
