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.

Converting kilopascals to pounds per square inch
To convert kilopascals to pounds per square inch, multiply the value by 0.14503774. 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.
Frequently asked questions
How many pounds per square inch are in one kilopascal?
1 kPa equals 0.14503774 psi.
How do I convert kilopascals to pounds per square inch?
Multiply the value by 0.14503774. For example, 10 kPa equals 1.4503774 psi.
How do I convert back from pounds per square inch to kilopascals?
1 psi equals 6.8947573 kPa. 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.
