About pounds-force per square inch and kilopascals
Pound-force per square inch (psi)
Pound-force per square inch is about 6,894.757 pascals. It is used for tire pressure and hydraulic and pneumatic systems in the US.
Kilopascal (kPa)
A kilopascal is 1,000 pascals. It is used for tire pressure, weather and engineering pressure ratings.
Both are units of pressure; the base unit used internally is Pa.
Notes
- Standard atmosphere = 101,325 Pa; bar = 100,000 Pa; psi = pound-force per square inch using standard gravity (≈ 6894.757 Pa).
- mmHg is the conventional millimeter of mercury (133.322387415 Pa) and the torr is exactly 1/760 of a standard atmosphere (≈ 133.3224 Pa); the two differ by about 0.000014 %.
- Absolute and gauge pressure are not distinguished: no gauge offset is applied. Negative values are accepted so that gauge vacuum readings can be converted.
psi to kPa FAQs
How do I convert pounds-force per square inch to kilopascals?
Multiply the number of pounds-force per square inch by 6.894757293 to get kilopascals. For example, 25 psi × 6.894757293 = 172.369 kPa.
How many kilopascals are in one pound-force per square inch?
1 psi = 6.894757293 kPa and 1 kPa = 0.1450377377 psi. To go the other way, use the kilopascals to pounds-force per square inch converter.
How many kilopascals are in 100 pounds-force per square inch?
100 psi = 689.476 kPa, rounded to 6 significant digits. Change the value in the converter above for any other amount.
How many kilopascals are in 35 pounds-force per square inch?
35 psi = 241.317 kPa, rounded to 6 significant digits.
What is the formula for pounds-force per square inch to kilopascals?
kPa = psi × 6.894757293, where psi is the number of pounds-force per square inch and kPa is the result in kilopascals. The reverse is psi = kPa × 0.1450377377.
Is the psi to kPa conversion exact?
The ratio is exact by definition, but its decimal form does not end (6.89475729317… to 12 significant digits). The converter keeps full precision internally and rounds only the displayed answer, which you can set from 4 to 12 significant digits.
What is the difference between pounds-force per square inch and kilopascals?
Pound-force per square inch is about 6,894.757 pascals. It is used for tire pressure and hydraulic and pneumatic systems in the US. A kilopascal is 1,000 pascals. It is used for tire pressure, weather and engineering pressure ratings.
Does this handle gauge pressure (psig) or absolute pressure (psia)?
The converter changes units only and does not add or remove atmospheric pressure. A reading of 30 psi is 206.843 kPa in whichever reference (gauge or absolute) it was measured; to move between gauge and absolute, add or subtract about 101.325 kPa (one standard atmosphere) yourself.
