Bar to Meters of Head Converter
1 bar equals 10.197 meters of water column at 4°C (SG=1.0). The factor 10.197 comes from the hydrostatic equation: pressure = density × g × height. For fluids with different...

Examples
1 bar
= 10.2 m
- SG = 1
1 bar = 10.2 m of water
5 bar
= 51 m
- SG = 1
5 bar = 51 m of water
10 bar
= 127.5 m
- SG = 0.8
10 bar of kerosene (SG 0.8) = 127.5 m head
Quick Reference Table
| bar | m head |
|---|---|
| 0.5 | 5.1 |
| 1 | 10.2 |
| 2 | 20.4 |
| 5 | 51 |
| 10 | 102 |
| 20 | 203.9 |
Where is this used?
This converter allows direct comparison between pump discharge pressure (from a gauge) and the pump's head curve, adjusted for fluid density.
Frequently Asked Questions
Where does 10.197 come from?
10.197 = 100,000 Pa/bar ÷ (1000 kg/m³ × 9.80665 m/s²). It is the height of a 1 bar water column at standard gravity.
How do I convert meters of head to bar?
Use the inverse: bar = m × SG ÷ 10.197. For water, 10 m head ≈ 0.981 bar.
Does this work for all liquids?
Yes, as long as you input the correct specific gravity for the liquid at operating temperature. For viscous fluids, additional pump correction factors may apply.
