How to Convert Kilogram-force per Square Centimetre to Millimeter of Mercury
- 1 kgf/cm² = 735.5591353 mmHg
- 1 mmHg = 0.00135951 kgf/cm²
- Example: convert 15 kgf/cm² to mmHg: 15 kgf/cm² = 15 × 735.5591353 mmHg = 11033.38703 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 = kgf/cm² × 735.5591352767
Derivation from SI units:
- 1 kgf/cm² = 9.80665 N ÷ 10⁻⁴ m² = 98 066.5 Pa (exact), also called the technical atmosphere (at)
- 1 mmHg = 13 595.1 kg/m³ × 9.80665 m/s² × 0.001 m = 133.322387415 Pa
- 1 kgf/cm² = 98066.5 Pa ÷ 133.322387415 Pa per mmHg = 735.5591352767 mmHg
Both units are defined exactly, so the factor is exact. Kilogram-force per Square Centimetre definition: kilogram-force per square centimetre; Millimeter of Mercury definition: millimeter of mercury.
Worked examples
- A reading of 7 kgf/cm² converts to 5148.913947 mmHg.
7 kgf/cm² × 735.5591353 = 5148.913947 mmHg - A value of 100 kgf/cm² is 73555.91353 mmHg.
100 kgf/cm² × 735.5591353 = 73555.91353 mmHg

Where it's used
Kilograms-force per Square Centimetre are used for pressure gauges in India, Japan and Latin America, 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.
