Pressure Unit Definitions
Practical Applications
HVAC Systems: Often use inches of water column (inH₂O) to measure static pressure in ductwork. 1 inH₂O ≈ 0.0361 psi.
Hydraulic Systems: Typically measured in PSI or bar. 1 bar ≈ 14.5 psi.
Tire Pressure: Usually measured in PSI (cars) or kPa (some international standards).
Medical Applications: Blood pressure is measured in mmHg, with normal being around 120/80 mmHg.
Scuba Diving: Tank pressure is measured in PSI or bar, with full tanks around 3000 psi (207 bar).
Key Conversion Formulas
1 atm = 101325 Pa = 1.01325 bar = 14.6959 psi = 760 mmHg = 760 torr
1 bar = 100000 Pa = 0.986923 atm = 14.5038 psi
1 psi = 6894.76 Pa = 0.0689476 bar = 51.7149 torr
1 mmHg = 1 torr = 133.322 Pa
1 inH₂O = 249.082 Pa (at 4°C)
