How to convert bar to pascals
1 bar = 100,000 pascals. To convert bar to pascals, multiply by 100,000. A bar is exactly 100,000 pascals, close to one atmosphere (1.01325 bar). The pascal is the SI unit of pressure, one newton per square meter.
Worked examples
- 1 bar = 100,000 Pa (1 × 100,000)
- 2.5 bar = 250,000 Pa (2.5 × 100,000)
- 100 bar = 10,000,000 Pa (100 × 100,000)
Where this conversion comes up
Bar are used for tire pressure in Europe, scuba tanks, espresso machines and weather; pascals for physics and sound pressure. Physics and engineering formulas need SI pascals, but gauges and equipment read bar. A bar is defined as exactly 100,000 Pa, so 1.5 bar is 150,000 Pa. Standard atmosphere (1.01325 bar) is 101,325 Pa.
Quick estimate
Multiply by 100,000: 2 bar = 200,000 Pa (or 200 kPa).
Common mistakes
- Dividing instead of multiplying. A pascal is smaller than a bar, so the number of pascals must come out larger: 1 bar = 100,000 Pa.
