How to Convert Kilogram-force per Square Millimetre to Inch of Mercury
- 1 kgf/mm² = 2895.902107 inHg
- 1 inHg = 0.00034531554 kgf/mm²
- Example: convert 15 kgf/mm² to inHg: 15 kgf/mm² = 15 × 2895.902107 inHg = 43438.53161 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/mm² × 2895.902107389
Derivation from SI units:
- 1 kgf/mm² = 9.80665 N ÷ 1 mm² = 9.80665 MPa (exact)
- 1 inHg = 13 595.1 kg/m³ × 9.80665 m/s² × 0.0254 m = 3386.388640341 Pa
- 1 kgf/mm² = 9806650 Pa ÷ 3386.388640341 Pa per inHg = 2895.902107389 inHg
Both units are defined exactly, so the factor is exact. Kilogram-force per Square Millimetre definition: kilogram-force per square millimetre; Inch of Mercury definition: inch of mercury.
Worked examples
- A reading of 24 kgf/mm² converts to 69501.65058 inHg.
24 kgf/mm² × 2895.902107 = 69501.65058 inHg - A value of 50 kgf/mm² is 144795.1054 inHg.
50 kgf/mm² × 2895.902107 = 144795.1054 inHg

Where it's used
Kilograms-force per Square Millimetre are used for tensile strength in older JIS and GB steel standards, 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.
