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.
Is mechanical hp the same as metric horsepower?
No. This tool uses mechanical horsepower, not metric horsepower (PS or cv). It also does not convert kilowatt-hours, which measure energy.
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.
