Converting pounds per square inch to kilopascals

To convert pounds per square inch to kilopascals, multiply the value by 6.8947573. Pressure conversions link structural loading, material strength grades and mechanical system ratings across metric and US practice.

PSI (psi)

Pounds per square inch (psi) is the pressure unit of US customary engineering.

Origin
Derived from the avoirdupois pound-force acting on one square inch.
Where it is used
Used for piping, pneumatics, hydraulic systems and US material strengths.
Relation to SI
1 psi = 6,894.757 Pa, about 6.895 kPa.

Kilopascal (kPa)

The kilopascal (kPa) equals 1,000 pascals.

Origin
A decimal multiple of the SI pascal.
Where it is used
Used for imposed floor loads, soil bearing pressure and wind loading in codes.
Relation to SI
1 kPa = 1,000 Pa = 1 kN/m².

Frequently asked questions

How many kilopascals are in one pound per square inch?

1 psi equals 6.8947573 kPa.

How do I convert pounds per square inch to kilopascals?

Multiply the value by 6.8947573. For example, 10 psi equals 68.947573 kPa.

How do I convert back from kilopascals to pounds per square inch?

1 kPa equals 0.14503774 psi. The converter above works in both directions, so you can type into either field.

How does pressure relate to structural loading?

One kilopascal equals one kilonewton per square meter, which is why imposed floor loads and wind pressures are stated in kPa or kN/m².

Why are concrete and steel grades given in MPa?

One megapascal equals one newton per square millimeter, which matches the millimeter cross-sections used in structural design, so C30/37 or S355 read directly as stress limits.

Is this pressure converter free to use?

Yes. Every unit conversion runs in your browser, needs no account and is free for professional use.
