How it is computed
bar = psi × 6,894.757 ÷ 100,000. One psi is one pound-force (0.45359237 kg × 9.80665 m/s²) on one square inch (0.0254 m)², and 1 bar is 100,000 Pa.
FAQ
Is tire pressure gauge (above air) pressure?+
Yes. Tire and compressor readings are gauge pressure, above the surrounding air; the conversion is the same for gauge and absolute values.
How do I convert bar to psi?+
Multiply bar by about 14.504. The calculator converts both ways.
