Explanation

Pressure factors here are derived from exact pascal-based definitions. Base constants include 1 kPa = 1000 Pa, 1 bar = 100000 Pa, 1 atm = 101325 Pa, plus exact psi and mmHg constants.

How to use this hub

  1. Choose a converter family.
  2. If converting to/from grams from a volume unit, select an ingredient.
  3. For pure unit changes (volume↔volume or weight↔weight), use universal conversions.

If your conversion includes grams, you’ll choose an ingredient; otherwise you won’t.

Frequently Asked Questions

How are these pressure factors derived?

Each factor is derived through pascals so bar, atm, psi, and mmHg conversions remain internally consistent.

Are these pressure ratios fixed?

Yes. They are based on exact base definitions and fixed constants, so conversion factors are stable and reproducible.
