How to convert pounds per square inch to kilopascals
- Take the value in pounds per square inch.
- Use the formula kilopascals = pounds per square inch × 6.894757293.
- For example, 35 psi is 241.32 kPa.
About pounds per square inch and kilopascals
One psi is 6.89476 kilopascals, so multiply psi by 6.89476 to get kPa. A quick estimate is to multiply by 7 and take off 1.5%: 30 psi gives about 207 kPa against the exact 206.84 kPa.
The kilopascal is the SI unit for everyday pressures. Tire placards in Canada, Australia and many other countries give kPa, often next to psi, and engineering specs, weather data and lab equipment use it too.
Examples
- 35 psi (a typical car tire pressure) is 241.32 kPa
- 14.7 psi (air pressure at sea level) is 101.35 kPa
- 15 psi (a stovetop pressure cooker at full pressure) is 103.42 kPa
- 12.5 psi (the NFL’s minimum football pressure) is 86.18 kPa
