About Kilopascals to PSI
Convert kilopascals to psi instantly, with a reference table of common values. The factor is exact: 1 kPa = 0.145037738 psi.
Used in automotive work, where tyre placards in metric countries state kilopascals while most gauges read psi.
The kilopascal is 1,000 pascals, the pascal being the SI unit of pressure โ one newton per square metre. The pascal alone is inconveniently small for everyday pressures, hence the kilo prefix. It is the standard pressure unit in scientific work and in the automotive and meteorological standards of many metric countries. Atmospheric pressure at sea level is about 101.3 kPa, and one kPa is about 0.145 psi.
Worked through with real numbers: 1 kPa is 0.145038 psi, 15 kPa is 2.176 psi, 30 kPa is 4.351 psi.
As for the other side of the conversion: car tyres are typically inflated to 30 to 35 psi, and atmospheric pressure at sea level is about 14.7 psi.
Pressure is force divided by area, so every pressure unit combines two other units. The values cluster near everyday atmospheric pressure โ about 14.7 psi, 1.013 bar or 101.3 kPa โ because most practical scales were built around it.

Frequently asked questions
How do I convert kilopascals to psi?
Multiply your kilopascals figure by 0.145037738 to get psi โ or type a value above and read the answer straight off.
How many psi are in one kilopascal?
1 kPa = 0.145037738 psi.
When would I need to convert kilopascals to psi?
Used in automotive work, where tyre placards in metric countries state kilopascals while most gauges read psi.
What is a kilopascal, exactly?
The kilopascal is 1,000 pascals, the pascal being the SI unit of pressure โ one newton per square metre. The pascal alone is inconveniently small for everyday pressures, hence the kilo prefix. Atmospheric pressure at sea level is about 101.3 kPa, and one kPa is about 0.145 psi.
Where is the psi actually used?
It is the standard for tyre pressure, hydraulics and compressed gas in the United States, and appears on tyre gauges worldwide. Car tyres are typically inflated to 30 to 35 psi, and atmospheric pressure at sea level is about 14.7 psi.
Is there anything tricky about pressure conversions?
Pressure is force divided by area, so every pressure unit combines two other units. The values cluster near everyday atmospheric pressure โ about 14.7 psi, 1.013 bar or 101.3 kPa โ because most practical scales were built around it.
Is this converter accurate?
Yes. It uses the exact standard factor of 1 kPa = 0.145037738 psi, and the conversion runs in your browser so nothing is uploaded.
