What is a pressure converter?
A pressure converter is an online tool that lets you quickly and accurately convert between pressure units. It supports pascals, hectopascals, kilopascals, bars, atmospheres, PSI and millimeters of mercury (mmHg).
What is pressure?
Pressure is the force applied perpendicular to a surface per unit area. It is measured in various units depending on the field: meteorologists use hectopascals, engineers use bars or PSI, and doctors use millimeters of mercury.
What are the pressure conversion formulas?
Key pressure conversion formulas:
- 1 atmosphere (atm) = 101,325 pascals (Pa)
- 1 bar = 100,000 pascals
- 1 atmosphere = 1.01325 bar
- 1 atmosphere = 14.696 PSI
- 1 atmosphere = 760 mmHg
- 1 hectopascal (hPa) = 100 pascals
- 1 kilopascal (kPa) = 1000 pascals
Pressure conversion examples
Weather: 1013.25 hPa = 1 atm. Standard atmospheric pressure at sea level as used in weather forecasts.
Tire pressure: 32 PSI = 2.21 bar. A typical recommended tire pressure for passenger cars.
Blood pressure: 120 mmHg = 16 kPa. A normal systolic blood pressure reading.
When to use a pressure converter?
A pressure converter is useful for checking tire pressure, reading weather reports, understanding medical measurements like blood pressure or working with industrial and engineering specifications where pressure units vary by region and industry.
