About this pressure converter: pa, bar, psi, atm, mmhg, hpa, torr

Convert seven pressure units locally, with gauge/absolute pressure notes and a qualified tire-pressure example Computes exact algebraic and numerical metrics directly in your browser using IEEE 754 precision without round-trip latency.

Formula & calculation mechanics

Enter a signed decimal and select its unit. All seven results keep the same pressure reference. Changing units keeps and reinterprets the number.

Worked numerical calculation

Scenario: 2.4 bar = 240000 Pa = 2400 hPa ≈ 34.8090570553 psi.

Sample input:

2.4 bar

Processing: Conventional mmHg uses 13595.1 × 9.80665 × 0.001 = 133.322387415 Pa; 1 Torr = 101325/760 Pa. They are close, not identical. 1 atm = 101325 Pa; 1 bar = 100000 Pa; 1 hPa = 100 Pa.

Illustrative output:

240000 Pa; 2400 hPa; ≈34.8090570553 psi

Domain range & precision boundaries

At most 64 characters; decimal point or scientific notation; |value|≤10¹⁰⁰. Binary64, up to 12 significant digits; tiny inputs may round to zero. Legacy JSON retains its original rounded factors. Unit conversion does not convert gauge pressure to absolute pressure: p_abs = p_gauge + p_ambient. A negative value may represent a pressure difference; it is not a negative absolute pressure. No ambient pressure is assumed. Illustration only: 2.3–2.5 bar ≈ 33.36–36.26 psi, not a universal safe range. Use the vehicle placard or owner’s manual for the specified load and tire size, including different front/rear settings. Check cold tires (not driven for at least three hours); the tire sidewall maximum is not the vehicle’s recommended pressure.
