How we calculated this For estimating and educational purposes only. Results are approximate and are not a substitute for a licensed professional, the manufacturer's instructions or your local code. Disclaimer
How to read the chart Find your value in the first column and read across. For units not listed, use the factor matrix: multiply by the number where your unit's row meets the target column. Gauge readings (tires, compressors) are above atmospheric pressure; add 1.013 bar (14.7 psi) for absolute pressure.
Frequently asked questions
How do I convert bar to psi quickly? Multiply by 14.5. For exact work use 14.5038.
Is kgf/cm² the same as bar? Almost: 1 kgf/cm² = 0.980665 bar, about 2% less.
