📊 Understanding Pressure Units

Pressure is the force applied perpendicular to a surface per unit area. Different fields use different units:

📊 Common Pressure Conversions

Atmospheric Pressure (1 atm):
• 1 atm = 101,325 Pa = 101.325 kPa = 0.1013 MPa
• 1 atm = 1.01325 bar = 14.6959 psi = 760 torr

Common Conversions:
• 1 bar = 100 kPa = 14.5038 psi
• 1 psi = 6.89476 kPa = 0.0689476 bar
• 1 torr = 133.322 Pa = 0.0193368 psi

❓ Frequently Asked Questions

How do I convert psi to bar?
Divide psi by 14.5038. For example, 30 psi ÷ 14.5038 = 2.07 bar. Our converter does this automatically.
What is standard atmospheric pressure in psi?
Standard atmospheric pressure at sea level is 14.6959 psi (approximately 14.7 psi).
What is the difference between bar and millibar?
1 bar = 1000 millibars (mbar). Millibars are commonly used in weather reports.
What is a Pascal in practical terms?
One Pascal is a very small pressure - roughly the pressure exerted by a sheet of paper resting on a table. That's why kilopascals (kPa) and megapascals (MPa) are more commonly used.
