Formula and example

How it is calculated

Converted value = original value × source factor / target factor

Worked example

1 bar = 100000 Pascal (Pa).

Things to check

  • 1 bar equals 100,000 Pa. Absolute pressure and gauge pressure have different reference points, even when their units match.
  • Rounding is applied only to displayed results. Very small or very large values may appear in scientific notation.
