How to convert bar to kilopascals
1 bar = 100 kilopascals. To convert bar to kilopascals, multiply by 100. A bar is exactly 100,000 pascals, close to one atmosphere (1.01325 bar). A kilopascal is 1,000 pascals; standard atmospheric pressure is 101.325 kPa.
Worked examples
- 1 bar = 100 kPa (1 × 100)
- 2.5 bar = 250 kPa (2.5 × 100)
- 10 bar = 1,000 kPa (10 × 100)
Where this conversion comes up
Bar are used for tire pressure in Europe, scuba tanks, espresso machines and weather; kilopascals for tire pressure outside the US, weather and engineering. Tire and boiler pressures in Europe are listed in bar, while engineering and automotive specs in many other places use kPa. A bar is exactly 100 kPa, so the conversion is a shift of two decimal places: a 2.2 bar tire is 220 kPa.
Quick estimate
Multiply by 100: 3 bar = 300 kPa. Standard atmosphere (101.325 kPa) is 1.01325 bar.
Common mistakes
- Dividing instead of multiplying. A kilopascal is smaller than a bar, so the number of kilopascals must come out larger: 1 bar = 100 kPa.
