kPa to PSI Converter
Use this kPa to PSI converter for low-pressure checks, HVAC static pressure, tire-pressure references, and equipment specs where metric pressure needs a PSI equivalent.
This page helps with searches such as 2.4 kpa to psi, 100 kpa to psi, and 220 kpa to psi when you need a fast result and a formula you can verify.
Quick examples

Where this conversion is commonly used
- Useful for HVAC static pressure and low-pressure readings that are documented in kPa but compared in PSI.
- Useful for tire, compressor, and workshop labels where pressure values move between metric and US-style gauges.
- Useful for equipment datasheets that publish kPa while a maintenance workflow expects PSI.
Frequently asked questions
What is 2.4 kPa in PSI?
2.4 kPa equals 0.34809 PSI.
How do you convert kPa to PSI?
Divide the kPa value by 6.89476. For example, 100 kPa equals 14.503768 PSI.
Why is a small kPa value such a small PSI value?
PSI is a larger pressure unit than kPa, so low kPa readings convert into fractional PSI values.
Should I round low-pressure results?
Use more decimals for low-pressure or HVAC static-pressure work, then round only for the final display.
