Formula: bar = GPa × 10,000
Reverse: GPa = bar × 0.0001
Step-by-Step Example
- Start with your value in Gigapascal. For example: 5 GPa
- Multiply by the conversion factor: 5 x 10,000
- The result is: 50,000 bar
About Gigapascal
The gigapascal (GPa) is a unit of pressure and stress. One gigapascal equals 1.000000 × 10^+9 pascals. UnitConvertLab converts it against every other pressure unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
Common uses: pressure calculations, engineering and science, education.
About Bar
The bar is a metric unit of pressure equal to 100,000 Pascals, roughly equal to atmospheric pressure at sea level.
Common uses: tire pressure, industrial, meteorology.
