- 1 bar
- = 100,000 Pa = 14.5038 psi = 750.062 mmHg
- 1 atm
- = 101,325 Pa = 14.6959 psi = 1.01325 bar = 760 mmHg
- 1 psi
- = 6,894.757 Pa = 0.068948 bar = 51.7149 mmHg
- 1 mmHg
- = 133.322 Pa = 0.019337 psi ≈ 1 Torr
- 1 inHg
- = 3,386.39 Pa = 33.8639 mbar (weather altimeters)
- 1 kgf/cm²
- = 98,066.5 Pa = 14.2233 psi (technical atmosphere)
- Gauge ⇄ Absolute
- Pabs = Pgauge + 1 atm (101,325 Pa)

All ten units share a single base: pascals. Each conversion is a multiplication by a fixed factor, so there's no rounding drift between adjacent conversions. Gauge and absolute readings differ by exactly one atmosphere (101,325 Pa). Tire gauges, boiler gauges, and sphygmomanometers all report gauge — aviation altimeters and vacuum equipment report absolute.
