How many Kilopascal (kPa) are in one PSI (psi)?

1 psi equals 6.89476 kPa. Multiply your PSI (psi) value by 6.89476 to get Kilopascal (kPa).

How do I convert PSI (psi) to Kilopascal (kPa)?

Use the formula kPa = psi × 6.89476. For example, 10 psi = 68.9476 kPa.

Direct Answer

1 psi = 6.89476 kPa

Formula: kPa = psi × 6.89476. This page supports instant conversion, reference table checks, and related unit links.

About this conversion

This Koverts page converts pounds per square inch (psi) to kilopascals (kPa) — common for tire pressure, HVAC, and industrial gauges across metric and US tooling.

PSI (pounds per square inch) expresses pressure as force per area in the US customary system. It appears on tire sidewalls, shop air compressors, and many US datasheets.

The kilopascal (kPa) is one thousand pascals and is widely used in metric countries for tire placards, building codes, and scientific pressure.

Typical uses

Matching tire pressure between psi gauge and kPa placard
Converting HVAC and duct pressure readings
Comparing hydraulic and shop air specifications
Science lab conversions from US equipment manuals

FormulakPa = psi × 6.89476

Common reference values

30 psi = 206.8428 kPa
32 psi = 220.63232 kPa
35 psi = 241.3166 kPa
100 psi = 689.476 kPa

Tip: Multiply psi by about 6.895 to get kPa. So 32 psi × 6.895 ≈ 220.6 kPa.

Did you know? Standard atmospheric pressure is about 14.696 psi — roughly 101.3 kPa — which is why “one atmosphere” shows up in both unit systems.

Educational reference - always verify critical measurements (medical, engineering, legal) with primary sources.

// Frequently Asked Questions

Is tire pressure “cold” or “hot” when people quote psi?▼

Vehicle placards usually specify cold inflation pressure (after the car has been parked for hours). Driving heats the tire and raises pressure temporarily — always follow the manufacturer’s label and check when cold for consistency.

Why do I see both bar and kPa on some gauges?▼

Bar is exactly 100 kPa (by definition), so dual scales help technicians who switch between workshop habits and metric documentation. Convert psi to kPa here, then divide by 100 if you need bar.

How many kPa is 1 psi?▼

1 psi ≈ 6.894757 kPa (more precisely, 1 psi = 6894.757293168 Pa, and 1 kPa = 1000 Pa). Multiply psi by about 6.895 to convert to kPa.

What is 1 psi in kPa?▼

1 psi = 6.89476 kPa.

How is the conversion calculated?▼

kPa = psi × 6.89476.

Can I convert other values?▼

Yes. Use the converter box above to enter any value and get instant results.
