How the calculation works
Pixels = relative value × entered font size in pixels. For REM use the root font; for EM use the relevant element font. The tool calculates entered values and does not inspect inheritance or a live page. Counts and dimensions use the declared rounding convention; other numbers display up to three decimal places where applicable. Nonzero subsecond durations are labelled. Durations round to the nearest second; nonzero subsecond durations are labelled. File-size output units are decimal. Changing an input label does not convert filled values.
Example
Worked example: REM Value = 1.5; Root Font Size = 16. Result: 24px.
Practical tip
Check the input labels and assumptions against the rem to pixels task before reusing the number.
