About the kPa to PSI Converter
Kilopascals and psi are the most common metric-imperial pressure pair. Tire labels, compressors, pumps, and equipment manuals often show one or both, so this conversion comes up constantly in everyday maintenance and engineering work.
This converter handles both directions and also shows bar, atm, Pa, and mmHg. That makes it useful when one device or manual uses kPa and another uses psi, especially in automotive, HVAC, and fluid-system contexts. It also gives a quick bridge when a spec sheet, gauge, or test report needs to be checked against a different unit system. That is especially useful for tire inflation, shop air, and hydraulic settings where the same value may appear in more than one format.
Use it when you need to move quickly between a metric pressure reading and a psi-based target or specification. It is most helpful when you want one clean value before comparing against a sticker, manual, or setpoint.
When This Page Helps
kPa is standard across metric documentation, while psi remains common on US gauges and many consumer products. This page bridges the two directly and keeps the nearby pressure units visible for reference. It is handy whenever the same pressure has to be checked against both metric and US-style labels, especially for tires, compressors, and hydraulic setpoints.
How to Use the Inputs
- Select the input unit from the dropdown menu.
- Enter your pressure value in the input field.
- View all converted values in the output cards below.
- Use the preset buttons for common values.
- Review the conversion table for a range of values.
- Expand the reference section to see real-world pressure examples.
- Check the quick formulas for the mathematical relationships.
Formula used
kPa to psi: psi = kPa × 0.145038
psi to kPa: kPa = psi × 6.89476
kPa to bar: bar = kPa ÷ 100
kPa to atm: atm = kPa ÷ 101.325Example Calculation
Result: 31.91 psi
220 kPa × 0.145038 = 31.91 psi. This is a typical passenger car tire pressure (often recommended as 32 psi or 220 kPa).
Tips & Best Practices
- Tire pressure on North American sidewalls: both kPa and psi are shown.
- Quick estimate: kPa ÷ 7 ≈ psi (within 1.5% accuracy).
- Standard tire pressures: 220-250 kPa = 32-36 psi for most cars.
- Water pressure at house faucet: about 300-500 kPa = 44-73 psi.
- 1 psi = 6.89476 kPa — memorize this for frequent conversions.
- TPMS sensors in cars typically alert below 175 kPa (25 psi).
Tire Pressure: kPa vs PSI
North American tires display maximum pressure in both psi and kPa on the sidewall. However, the recommended pressure (found on the driver door sticker) may only show one unit. Typical values: compact cars 200-220 kPa (29-32 psi), sedans 220-240 kPa (32-35 psi), trucks/SUVs 240-280 kPa (35-41 psi).
Engineering Standards
ISO and metric engineering standards specify pressures in kPa, MPa, or bar. ASME and US standards use psi. When working with international projects, engineers must convert frequently between these systems.
Water and Hydraulic Systems
Residential water pressure: 275-550 kPa (40-80 psi). Fire hydrant minimum: 1,380 kPa (200 psi). Hydraulic systems: 7,000-35,000 kPa (1,015-5,076 psi). Industrial hydraulic presses can exceed 70,000 kPa (10,153 psi).

Frequently Asked Questions
200 kPa = 29.01 psi. That is slightly below the typical car tire pressure of 32 psi (220 kPa), so it is a useful checkpoint when reading mixed-unit labels.
Multiply kPa by 0.145038, or divide by 6.89476. For example, 300 kPa × 0.145038 = 43.51 psi, which is a common shop-air or hydraulic reference range.
Most passenger cars specify 200-250 kPa, which is about 29-36 psi. Check the sticker on your driver door jamb for the exact recommendation because the correct target depends on vehicle and load.
PSI is dominant in the US, while kPa is standard in Canada, Australia, and most metric countries. International standards often use kPa or bar, so the converter is useful when your sources do not match.
Municipal water pressure is typically 275-550 kPa, or about 40-80 psi. Low water pressure is below 207 kPa, while pressures above 550 kPa are often considered high for residential plumbing.
Multiply psi by 6.89476. For example, 32 psi × 6.89476 = 220.6 kPa, which is the same relationship used when converting tire specs to metric.
