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.

Are these troy ounces?

No. The ounce and pound here are avoirdupois mass units. Precious-metal troy ounces and force units are not included.

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.
