How to Convert Megapascal to Millimeter of Mercury
- 1 MPa = 7500.615758 mmHg
- 1 mmHg = 0.0001333223874 MPa
- Example: convert 15 MPa to mmHg: 15 MPa = 15 × 7500.615758 mmHg = 112509.2364 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 = MPa × 7500.615758457
Derivation from SI units:
- 1 MPa = 10⁶ Pa = 1 N/mm²
- 1 mmHg = 13 595.1 kg/m³ × 9.80665 m/s² × 0.001 m = 133.322387415 Pa
- 1 MPa = 1000000 Pa ÷ 133.322387415 Pa per mmHg = 7500.615758457 mmHg
Both units are defined exactly, so the factor is exact. Megapascal definition: megapascal; Millimeter of Mercury definition: millimeter of mercury.
Worked examples
- A reading of 2 MPa converts to 15001.23152 mmHg.
2 MPa × 7500.615758 = 15001.23152 mmHg - A value of 30 MPa is 225018.4728 mmHg.
30 MPa × 7500.615758 = 225018.4728 mmHg

Where it's used
Megapascals are used for concrete compressive strength (typically 20–50 MPa), 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.

Frequently asked questions
How many millimeters of mercury are in 1 megapascal?
1 MPa = 7500.615758 mmHg.
How do I convert megapascals to millimeters of mercury?
Multiply the value in MPa by 7500.615758. For example, 15 MPa × 7500.615758 = 112509.2364 mmHg.
Is the MPa to mmHg conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
