Frequently Asked Questions
Is kPa the same as psi?
They measure the same physical quantity but with different units. 1 psi ≈ 6.895 kPa. kPa is the preferred SI unit in most engineering contexts outside the US.
How do I convert kPa to bar?
Divide kPa by 100. So 500 kPa = 5 bar. The relationship is exact: 1 bar = 100 kPa.
What is typical atmospheric pressure in kPa?
Standard atmospheric pressure is 101.325 kPa (14.696 psi or 1.01325 bar) at sea level.
