How to Convert Kilogram-force per Square Centimetre to Inch of Mercury
- 1 kgf/cm² = 28.95902107 inHg
- 1 inHg = 0.034531554 kgf/cm²
- Example: convert 15 kgf/cm² to inHg: 15 kgf/cm² = 15 × 28.95902107 inHg = 434.3853161 inHg
Reference conditions. inHg: Conventional mercury column: ρ = 13 595.1 kg/m³ and gₙ = 9.80665 m/s² (≈ mercury at 0 °C / 32 °F).
Formula
inHg = kgf/cm² × 28.95902107389
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 inHg = 13 595.1 kg/m³ × 9.80665 m/s² × 0.0254 m = 3386.388640341 Pa
- 1 kgf/cm² = 98066.5 Pa ÷ 3386.388640341 Pa per inHg = 28.95902107389 inHg
Both units are defined exactly, so the factor is exact. Kilogram-force per Square Centimetre definition: kilogram-force per square centimetre; Inch of Mercury definition: inch of mercury.
Worked examples
- A reading of 7 kgf/cm² converts to 202.7131475 inHg.
7 kgf/cm² × 28.95902107 = 202.7131475 inHg - A value of 100 kgf/cm² is 2895.902107 inHg.
100 kgf/cm² × 28.95902107 = 2895.902107 inHg

Where it's used
Kilograms-force per Square Centimetre are used for pressure gauges in India, Japan and Latin America, while inches of mercury appear in aircraft altimeter settings (standard 29.92 inHg). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
