Worked examples

Try punctuation, repeated spaces and line breaks so you can see exactly what the transformation preserves.
Unicode
Test accented or non-Latin characters if the output will be used with multilingual text.
Understanding the result
The output should be read in the units shown beside the result. If you are comparing alternatives, keep all unchanged assumptions identical and alter one input at a time. That makes it easier to see which value is responsible for the difference.
Assumptions, edge cases and accuracy
Check the units, input meaning and displayed rounding before relying on the result. The calculator does not add information that was not supplied in its inputs.
