kPa to PSI Converter
Updated Formulas shown
Divide kilopascals by 6.89476 (or multiply by 0.145038) to get psi: 220 kPa = 31.9 psi. Canadian and Australian tire placards are printed in kPa.
Formula: pounds per square inch = kilopascals ÷ 6.8947572932 (exact ratio, shown rounded)

How to convert kilopascals to pounds per square inch
- Type the value in kilopascals into the converter (or into the right-hand box to go the other way).
- Divide by 6.8947572932 to get pounds per square inch.
- Round to a sensible precision with the Decimals control; the table below covers the values people look up most.
Kilopascal to pound per square inch formula
pounds per square inch = kilopascals ÷ 6.8947572932 — 1 kPa = 0.14503774 psi. Both units are defined exactly (NIST SP 811); the factor above is rounded to 10 decimals, and the converter uses the full-precision ratio.

Structural loads: psf and kPa
| psf | kPa | typical load |
|---|---|---|
| 10 | 0.48 | Roof dead load (shingles) |
| 20 | 0.96 | Light ground snow load |
| 30 | 1.44 | Bedroom live load (IRC) |
| 40 | 1.92 | Living area and deck live load (IRC) |
| 50 | 2.39 | Moderate ground snow load |
| 100 | 4.79 | Heavy snow region |
Loads are pressures too
Snow and floor loads are a force per area, so they convert like pressure: 40 psf (the IRC live load for decks and living areas) is 1.92 kPa. Metric codes give the same loads in kPa or kN/m² (identical units). Use psf when you size joists from US span tables.
