Science Guide
Understanding Pressure Units
🔹 1 Pa = 1 N/m² (base SI unit)
🔹 1 bar = 100,000 Pa ≈ 14.5038 psi
🔹 1 atm = 101,325 Pa = 1.01325 bar = 14.6959 psi
🔹 1 torr = 1 mmHg = 133.322 Pa
🔹 1 bar = 100,000 Pa ≈ 14.5038 psi
🔹 1 atm = 101,325 Pa = 1.01325 bar = 14.6959 psi
🔹 1 torr = 1 mmHg = 133.322 Pa
Tire Pressure
Car tires: 30-35 psi ≈ 2.07-2.41 bar. Bicycle tires: 40-80 psi.
Water Pressure
Diving: 10 m depth adds 1 atm (≈ 100 kPa, 14.5 psi).
Atmospheric Pressure
Sea level: 1 atm, 1013 mbar, 14.7 psi. Decreases with altitude.
FAQs
How do I convert PSI to Bar?+
Multiply PSI by 0.0689476 to get bar. For example, 32 psi × 0.06895 ≈ 2.21 bar. Our converter does it instantly.
What is the difference between PSI and PSIG?+
PSI is absolute pressure, PSIG is gauge pressure (relative to atmospheric). PSIG + 14.7 = PSI at sea level.
How many pascals are in 1 bar?+
1 bar = 100,000 Pa = 100 kPa = 0.1 MPa. Our converter supports all prefixes.
What is standard atmospheric pressure in mmHg?+
1 atm = 760 mmHg (torr). Weather reports often use mbar: 1013 mbar = 1 atm.
