How to Convert Kilopascal to Kilogram-force per Square Millimetre
- 1 kPa = 0.0001019716213 kgf/mm²
- 1 kgf/mm² = 9806.65 kPa
- Example: convert 15 kPa to kgf/mm²: 15 kPa = 15 × 0.0001019716213 kgf/mm² = 0.001529574319 kgf/mm²
Formula
kgf/mm² = kPa × 0.0001019716212978
or kgf/mm² = kPa ÷ 9806.65
Derivation from SI units:
- 1 kPa = 10³ Pa
- 1 kgf/mm² = 9.80665 N ÷ 1 mm² = 9.80665 MPa (exact)
- 1 kPa = 1000 Pa ÷ 9806650 Pa per kgf/mm² = 0.0001019716212978 kgf/mm²
Both units are defined exactly, so the factor is exact. Kilopascal definition: kilopascal; Kilogram-force per Square Millimetre definition: kilogram-force per square millimetre.
Worked examples
- A reading of 20 kPa converts to 0.002039432426 kgf/mm².
20 kPa × 0.0001019716213 = 0.002039432426 kgf/mm² - A value of 300 kPa is 0.03059148639 kgf/mm².
300 kPa × 0.0001019716213 = 0.03059148639 kgf/mm²

Where it's used
Kilopascals are used for tyre pressure outside the United States (about 200–250 kPa for cars), 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.
