About kilopascals and pounds-force per square inch

Kilopascal (kPa)

A kilopascal is 1,000 pascals. It is used for tire pressure, weather and engineering pressure ratings.

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.

Both are units of pressure; the base unit used internally is Pa.

Notes

kPa to psi FAQs

How do I convert kilopascals to pounds-force per square inch?

Multiply the number of kilopascals by 0.1450377377 to get pounds-force per square inch. For example, 25 kPa × 0.1450377377 = 3.62594 psi.

How many pounds-force per square inch are in one kilopascal?

1 kPa = 0.1450377377 psi and 1 psi = 6.894757293 kPa. To go the other way, use the pounds-force per square inch to kilopascals converter.

How many pounds-force per square inch are in 350 kilopascals?

350 kPa = 50.7632 psi, rounded to 6 significant digits. Change the value in the converter above for any other amount.

How many pounds-force per square inch are in 300 kilopascals?

300 kPa = 43.5113 psi, rounded to 6 significant digits.

What is the formula for kilopascals to pounds-force per square inch?

psi = kPa × 0.1450377377, where kPa is the number of kilopascals and psi is the result in pounds-force per square inch. The reverse is kPa = psi × 6.894757293.

Is the kPa to psi conversion exact?

The ratio is exact by definition, but its decimal form does not end (0.14503773773… 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 kilopascals and pounds-force per square inch?

A kilopascal is 1,000 pascals. It is used for tire pressure, weather and engineering pressure ratings. 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.

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 kPa is 4.35113 psi in whichever reference (gauge or absolute) it was measured; to move between gauge and absolute, add or subtract about 14.6959 psi (one standard atmosphere) yourself.
