Practical tools for measured work

Speed converter

Convert speed between metres per second, kilometres per hour, mph and knots.

Calculate the layout, check the diagram, then print the result for the shop or jobsite.

How it works

Enter a value, choose its current unit and select the target unit. The table shows equivalent values within the same physical quantity. Signed values are supported; conversion does not change the meaning of a negative measurement.

36 km/h = 10 m/s; 1 mph = 0.44704 m/s

Speed is distance divided by time. A knot uses a nautical mile of 1852 metres per hour. This converter changes units; it does not calculate travel time or account for stops.

Before using the result

  • Check the selected mode, units and input values before using the result.
  • Read the assumptions and rounding rules; compare the worked example with your intended calculation.
  • A numerical result does not supply missing context or change the stated limitations.

Limitations

Results use floating-point arithmetic and are displayed to ten significant digits. This tool does not measure an object, infer missing dimensions or supply material density. Keep unrounded values for further calculations when precision matters.

Frequently asked questions

Why are some units missing from the list?

Only units of the same physical quantity can be selected together. Choose another converter for a different quantity; a length cannot become an area without another dimension.
