Tire Pressure Converter
Convert tire pressure between psi, bar, and kPa and compare common vehicle presets.
Note: Always follow the tire pressure label on your vehicle or the tire manufacturer specification.
Category: Life Tools
When to use?
Use it when a tire gauge or manual uses a different pressure unit than the one you need.
How to use
- Enter a pressure value.
- Choose the source unit.
- Check converted psi, bar, and kPa values.
Input Explanation
Enter the pressure in psi, bar, or kPa. Vehicle presets are only examples.
Calculation Basis
1 psi = 6.89476 kPa and 1 bar = 100 kPa.
Usage Examples
- Convert gauge readings - Match a pressure gauge reading to the unit in a manual.
- Check car presets - Use preset examples as a quick reference.
- Before long drives - Prepare the correct pressure unit before checking tires.
Examples
- 35 psi → about 2.41 bar, 241 kPa
- 2.5 bar → about 36.3 psi
Cautions
- This is an estimate for everyday planning. Actual results can vary by environment, product specifications, personal condition, and local rules.
Guides
Pressure unit basics
psi, bar, and kPa are different units for the same pressure. 1 bar is 100 kPa, and 1 psi is about 6.895 kPa.
Use official specs
The correct tire pressure is on your vehicle label or tire specification. Temperature and load can affect recommended pressure.
FAQ
Which value should I actually use?
Use your vehicle door label or official tire specification.
Are psi, bar, and kPa all supported?
Yes, values convert both ways.
Does temperature matter?
Yes, tire pressure changes with temperature, so measure under recommended conditions.
