Convert pounds per square inch (psi) to kilopascals (kPa), or kPa back to psi, with the standard pressure factor and adjustable decimal precision.

Here “lbs” means pounds-force per square inch (psi). Pounds alone cannot be converted to pressure without an area. The pressure reference is retained.

Lbs To kPa Formula

The following formula converts pounds-force per square inch (psi) to kilopascals (kPa). A value stated only in pounds of mass or force is insufficient.

kPa = psi × 6.894757293168361

Variables:

  • kPa is the pressure in kilopascals
  • psi is the pressure in pounds-force per square inch

Multiply psi by 6.894757293168361 to obtain kPa; divide kPa by the same factor for the reverse. Gauge or differential pressure retains its reference, and absolute pressure remains absolute. The calculator rejects negative absolute pressure.

What is Lbs To kPa?

This page converts pressure between psi (pounds-force per square inch) and kPa. Neither pounds of mass nor pounds-force alone is pressure; pressure requires force per area. This is a unit conversion, not a change between gauge and absolute reference systems.

How to Calculate Lbs To kPa?

The following steps convert pressure from psi to kPa using kPa = psi × 6.894757293168361.


  1. First, determine the pressure in pounds per square inch (Lbs).
  2. Next, multiply the pressure in psi by 6.894757293168361 to obtain kPa.
  3. Finally, calculate the pressure in kilopascals (kPa).
  4. After inserting the value of Lbs and calculating the result, check your answer with a calculator.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Pressure = 10 psi. Therefore 10 × 6.894757293168361 = 68.94757293168361 kPa, displayed as 68.948 kPa at 3 decimal places.
