Weather data (barometric pressure reported in kPa or hPa), vacuum pump specifications, and boiler pressure settings.
Frequently Asked Questions
How do I convert psi back to kPa?
Multiply psi by 6.89476. For quick estimates, multiply psi by 6.9 to get kPa.
What is the relationship between kPa and bar?
1 bar = 100 kPa exactly. So 300 kPa = 3 bar. This relationship is exact because both are derived from the pascal.
What is typical tire pressure in kPa?
Passenger car tire pressure is typically 200–300 kPa (30–44 psi). European car specs often list tire pressures in kPa.
