⚙️ kPa to psi Converter
Instantly convert pressure from kilopascals (kPa) to pounds per square inch (psi). Essential for tire pressure, pneumatic systems, and engineering applications.
What Is kPa and psi?
Kilopascal (kPa) is a metric unit of pressure equal to 1,000 pascals. It is widely used in engineering, meteorology, and everyday applications like tire pressure. The pound per square inch (psi) is an imperial unit of pressure commonly used in the United States for tire pressure, hydraulic systems, and industrial applications.
The conversion between these two units is:
- 1 kPa ≈ 0.145 psi
- 1 psi ≈ 6.895 kPa
- Standard Atmosphere: 101.325 kPa = 14.696 psi
How to Convert kPa to psi
The formula to convert kilopascals to pounds per square inch is:
psi = kPa × 0.1450377377
or psi = kPa ÷ 6.894757
For example, to convert 101.325 kPa (standard atmosphere) to psi:
psi = 101.325 × 0.1450377377
psi = 14.696 psi
To convert a typical car tire pressure of 220 kPa to psi:
psi = 220 × 0.1450377377
psi ≈ 31.9 psi
