Understanding Pressure Units
PSI (Pounds per Square Inch)
Common in US and UK. Used for:
- Tire pressure (32-35 PSI typical)
- Water pressure (40-60 PSI)
- Air compressors (90-150 PSI)
Bar
Metric unit popular in Europe. Used for:
- Atmospheric pressure (≈1.01325 bar)
- Hydraulic systems (200-300 bar)
- Pneumatic tools (6-8 bar)
Pascal (kPa, MPa)
SI unit of pressure:
- kPa: Weather and low pressure
- MPa: Industrial applications
- 1 MPa = 1000 kPa
