When do you need psi → bar?
Tire pressure in bar or psi, blood pressure in mmHg, pipelines in MPa — pressure units span cars, health and engineering. For example: cold tire pressure 2.5 bar ≈ 36.3 psi (door-jamb labels list both); blood pressure 120 mmHg ≈ 16 kPa.
Where do psi and bar come from?
SI anchors to the pascal (N/m²). Bar = 100 kPa from barometric practice; standard atmosphere = 101.325 kPa; psi = 6.895 kPa; mmHg (Torr) = 133.3 Pa, from Torricelli's mercury experiment.
FAQs
▸How many bars is 2 psi?
2 psi equals 0.137895 bars. Calculated as 2 × 0.068948 = 0.137895.
▸What is the formula to convert psi to bars?
1 psi = 0.068948 bar, so bar = psi × 0.068948
▸Is there a quick way to estimate psi to bar?
1 bar ≈ 14.5 psi ≈ 100 kPa ≈ 1 atm. Tire pressure: 2.5 bar ≈ 36 psi.
▸Where can I convert other values?
Open the full psi converter and enter any value: the tool supports bidirectional conversion between psi and bar with all related units.
▸Why does the result contain decimals? How is rounding handled?
Because psi and bar belong to different unit systems, the ratio is rarely a round number — results are shown to 6 significant figures and rounded for readability. For engineering or medical use, keep at least 2 decimal places and verify with the tool above.
▸Where do the psi and bar definitions come from?
Both units trace back to international standard definitions — imperial units were fixed against metric by the 1959 international yard-and-pound agreement, and metric units are maintained by the BIPM. The factors used on this page match those standards.
▸How do I convert bar back to psi?
Use the inverse operation: for linear conversions divide by the factor instead of multiplying (or visit the reverse page); for temperature pairs, apply the inverse formula shown in the formula section.
