Pressure units on gauges and specifications
Pounds per square inch and bar commonly appear together on tire, compressor, and equipment gauges. This converter changes only the unit; it does not determine a safe or recommended operating pressure.
- Use the vehicle placard or manufacturer specification for the target pressure.
- Check whether a value is gauge pressure or absolute pressure.
- Round to the resolution of the gauge you can actually read.
