Reading the result
Check the definitions of the source and target units. A conversion changes the representation of a measurement; it does not measure the quantity again. Round at the final step if you will reuse the result.
Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
What does a knot mean?
A knot is one nautical mile per hour, exactly 1.852 kilometres per hour. The tool converts speed, not travel duration.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
