How to Convert Torr to Kilogram-force per Square Millimetre
- 1 Torr = 0.00001359509806 kgf/mm²
- 1 kgf/mm² = 73555.92401 Torr
- Example: convert 15 Torr to kgf/mm²: 15 Torr = 15 × 0.00001359509806 kgf/mm² = 0.0002039264709 kgf/mm²
Formula
kgf/mm² = Torr × 0.00001359509806316
or kgf/mm² = Torr ÷ 73555.92400691
Derivation from SI units:
- 1 Torr = 101325/760 Pa = 133.3223684 Pa (1/760 of a standard atmosphere)
- 1 kgf/mm² = 9.80665 N ÷ 1 mm² = 9.80665 MPa (exact)
- 1 Torr = 133.3223684211 Pa ÷ 9806650 Pa per kgf/mm² = 0.00001359509806316 kgf/mm²
Both units are defined exactly, so the factor is exact. Torr definition: torr; Kilogram-force per Square Millimetre definition: kilogram-force per square millimetre.
Worked examples
- A reading of 0.1 Torr converts to 0.000001359509806 kgf/mm².
0.1 Torr × 0.00001359509806 = 0.000001359509806 kgf/mm² - A value of 100 Torr is 0.001359509806 kgf/mm².
100 Torr × 0.00001359509806 = 0.001359509806 kgf/mm²

Where it's used
Torr are used for vacuum technology and vacuum gauges, 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.
