How to Convert Kilogram-force per Square Millimetre to Millibar
- 1 kgf/mm² = 98066.5 mbar
- 1 mbar = 0.00001019716213 kgf/mm²
- Example: convert 15 kgf/mm² to mbar: 15 kgf/mm² = 15 × 98066.5 mbar = 1470997.5 mbar
Formula
mbar = kgf/mm² × 98066.5
Derivation from SI units:
- 1 kgf/mm² = 9.80665 N ÷ 1 mm² = 9.80665 MPa (exact)
- 1 mbar = 10⁻³ bar = 100 Pa = 1 hPa
- 1 kgf/mm² = 9806650 Pa ÷ 100 Pa per mbar = 98066.5 mbar
Both units are defined exactly, so the factor is exact. Kilogram-force per Square Millimetre definition: kilogram-force per square millimetre; Millibar definition: millibar.
Worked examples
- A reading of 24 kgf/mm² converts to 2353596 mbar.
24 kgf/mm² × 98066.5 = 2353596 mbar - A value of 50 kgf/mm² is 4903325 mbar.
50 kgf/mm² × 98066.5 = 4903325 mbar

Where it's used
Kilograms-force per Square Millimetre are used for tensile strength in older JIS and GB steel standards, while millibars appear in weather maps and barometers (sea level ≈ 1013 mbar). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
