How to Convert Gigapascal to Millimeter of Mercury
- 1 GPa = 7500615.758 mmHg
- 1 mmHg = 1.333223874 × 10⁻⁷ GPa
- Example: convert 15 GPa to mmHg: 15 GPa = 15 × 7500615.758 mmHg = 112509236.4 mmHg
Reference conditions. mmHg: Conventional mercury column: ρ = 13 595.1 kg/m³ and gₙ = 9.80665 m/s² (≈ mercury at 0 °C / 32 °F).
Formula
mmHg = GPa × 7500615.758457
Derivation from SI units:
- 1 GPa = 10⁹ Pa = 1000 MPa = 1 kN/mm²
- 1 mmHg = 13 595.1 kg/m³ × 9.80665 m/s² × 0.001 m = 133.322387415 Pa
- 1 GPa = 1000000000 Pa ÷ 133.322387415 Pa per mmHg = 7500615.758457 mmHg
Both units are defined exactly, so the factor is exact. Gigapascal definition: gigapascal; Millimeter of Mercury definition: millimeter of mercury.
Worked examples
- A reading of 10 GPa converts to 75006157.58 mmHg.
10 GPa × 7500615.758 = 75006157.58 mmHg - A value of 190 GPa is 1425116994 mmHg.
190 GPa × 7500615.758 = 1425116994 mmHg

Where it's used
Gigapascals are used for young's modulus and shear modulus of metals, ceramics and composites, while millimeters of mercury appear in blood pressure (e.g. 120/80 mmHg). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
