How to Convert Kilogram-force per Square Millimetre to Bar
- 1 kgf/mm² = 98.0665 bar
- 1 bar = 0.01019716213 kgf/mm²
- Example: convert 15 kgf/mm² to bar: 15 kgf/mm² = 15 × 98.0665 bar = 1470.9975 bar
Formula
bar = kgf/mm² × 98.0665
Derivation from SI units:
- 1 kgf/mm² = 9.80665 N ÷ 1 mm² = 9.80665 MPa (exact)
- 1 bar = 10⁵ Pa (exact, by definition)
- 1 kgf/mm² = 9806650 Pa ÷ 100000 Pa per bar = 98.0665 bar
Both units are defined exactly, so the factor is exact. Kilogram-force per Square Millimetre definition: kilogram-force per square millimetre; Bar definition: bar.
Worked examples
- A reading of 24 kgf/mm² converts to 2353.596 bar.
24 kgf/mm² × 98.0665 = 2353.596 bar - A value of 50 kgf/mm² is 4903.325 bar.
50 kgf/mm² × 98.0665 = 4903.325 bar
