How to convert bars to kilopascals
One bar is exactly 100 kPa, so the conversion is a simple ×100 — handy for weather maps (1 mbar = 1 hPa) and gauges.
To convert bars to kilopascals, use kPa = bar × 100. One bar equals 100 kilopascals, and one kilopascal equals 0.01 bars.
Bar (bar): Exactly 100,000 Pa. Kilopascal (kPa): 1,000 Pa.
All pressure units are on the pressure converter.
Limitations
- Results are rounded to the decimal places you choose; the calculation itself keeps full precision.
Frequently asked questions
How many kilopascals are in a bar?
1 bar = 100 kPa. Multiply bars by 100 (or use kPa = bar × 100).
How do I convert bars to kilopascals?
Use kPa = bar × 100. For example, 1 bar = 100 kPa and 10 bar = 1,000 kPa.
How many psi are in a bar?
1 bar = 14.5038 psi.
Is mmHg the same as torr?
Almost: 1 Torr = 133.3224 Pa and 1 mmHg = 133.3224 Pa differ only in the seventh significant digit. For everyday use they're interchangeable.
