Convert Kilograms-force per Square Centimetre to kgf/mm²

Formula

kgf/mm² = kgf/cm² ÷ 100

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 kgf/mm² = 9.80665 N ÷ 1 mm² = 9.80665 MPa (exact)
• 1 kgf/cm² = 98066.5 Pa ÷ 9806650 Pa per kgf/mm² = 0.01 kgf/mm²

Both units are defined exactly, so the factor is exact. Kilogram-force per Square Centimetre definition: kilogram-force per square centimetre; Kilogram-force per Square Millimetre definition: kilogram-force per square millimetre.

Worked examples

1. A reading of 7 kgf/cm² converts to 0.07 kgf/mm².
   7 kgf/cm² × 0.01 = 0.07 kgf/mm²
2. A value of 100 kgf/cm² is 1 kgf/mm².
   100 kgf/cm² × 0.01 = 1 kgf/mm²

Where it's used

Kilograms-force per Square Centimetre are used for pressure gauges in India, Japan and Latin America, while kilograms-force per square millimetre appear in tensile strength in older JIS and GB steel standards. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
