BAR Pressure Unit Reference
BAR is a unit of pressure equal to 14.7 psi, corresponding to atmospheric pressure at sea level. Essential for sensor readings and pressure conversions in automotive diagnostics.
Definition
BAR is a metric unit of pressure equal to 14.7 psi. It is also called an atmosphere (atm) because it corresponds to atmospheric pressure at sea level.
Conversion Formulas
| From | To | Formula |
|---|---|---|
| BAR | psi | psi = BAR Ã 14.7 |
| psi | BAR | BAR = psi ÷ 14.7 |
| BAR | kPa | kPa = BAR Ã 100 |
| kPa | BAR | BAR = kPa ÷ 100 |
Common Pressure Values
| Unit | Value |
|---|---|
| 1 BAR | 14.7 psi |
| 1 BAR | 100 kPa |
| 1 atm | 1 BAR |
Note
The SI unit for pressure is the Pascal (Pa) or Kilopascal (kPa). BAR is a derived metric unit commonly used in automotive applications, particularly for fuel pressure and boost pressure measurements.
