Pressure Conversion Guide

Medical & Weather

Normal blood pressure is 120/80 mmHg (16/10.7 kPa)

Blood pressure cuffs measure gauge pressure above atmospheric

Eye pressure (intraocular) is normally 10-21 mmHg (1.3-2.8 kPa)

Weather maps show pressure in millibars (hPa)

Low pressure systems (below 1000 mb) bring storms and rain

Industrial & Physics

Hydraulic systems commonly operate at 1000-3000 psi

Water jet cutters use pressures up to 90,000 psi (620 MPa)

Pressure = Force ÷ Area (P = F/A)

Gauge pressure = Absolute pressure - Atmospheric pressure

Quick Conversion Tips

Quick conversion: 1 bar ≈ 14.5 psi ≈ 100 kPa
1 atmosphere = 760 mmHg = 760 Torr = 29.92 inHg
PSI × 6.895 = kPa; kPa ÷ 6.895 = PSI
mmHg × 0.133 = kPa; kPa ÷ 0.133 = mmHg

Vacuum Applications

Perfect vacuum is 0 Pa absolute pressure

Laboratory vacuum pumps achieve 10⁻⁶ to 10⁻¹² Torr

Space has extremely low pressure (~10⁻¹⁷ Torr)

Vacuum packaging typically removes air to 50-100 mTorr

Extreme Pressures

Earth's core pressure: ~360 GPa (3.6 million atmospheres)

Diamond formation requires ~5 GPa pressure

Mariana Trench bottom: ~110 MPa (1100 atmospheres)

Lightning creates pressures exceeding 100 atmospheres
