Conversion formula
Linear unit conversions use standardized factors; many are exact by definition (e.g., 1 in = 25.4 mm, 1 ft = 0.3048 m).
Common mistakes
- Comparing gauge pressure (psig) with absolute pressure (psia/hPa) without converting reference.
- Mixing bar with atm (1 atm = 1.01325 bar).
Unit facts
- Torr: Torr is ≈133.322368 Pa; named after Torricelli (barometer). Used in vacuum science.
- Bar: One bar is exactly 100,000 Pa; convenient near-atmospheric unit used in meteorology and diving.
About Pressure
Pressure is force per unit area. Pascals (and kPa, hPa) are SI, while bar and psi are widely used in engineering and scuba. Conversions must respect absolute vs gauge references when comparing values.
About Torr
Torr
≈133.322 Pa. Preferred in high-vacuum work alongside millitorr and microns.
History: Named after Torricelli; bridges historical millimeters of mercury (mmHg) with SI pascals.
About Bar
Bar
Equals 100,000 Pa (exact). Handy engineering unit near mean sea-level pressure (≈1.01325 bar).
History: Introduced by early 20th-century meteorologists; remains popular in scuba, hydraulics, and weather.
