How to Convert Inch of Water (60 °F) to Kilogram-force per Square Millimetre
- 1 inH₂O (60 °F) = 0.00002537461824 kgf/mm²
- 1 kgf/mm² = 39409.45989 inH₂O (60 °F)
- Example: convert 15 inH₂O (60 °F) to kgf/mm²: 15 inH₂O (60 °F) = 15 × 0.00002537461824 kgf/mm² = 0.0003806192737 kgf/mm²
Reference conditions. inH₂O (60 °F): Water at 60 °F (15.6 °C), density ≈ 999.0 kg/m³, standard gravity. NIST value, 5 significant figures.
Formula
kgf/mm² = inH₂O (60 °F) × 0.00002537461824374
or kgf/mm² = inH₂O (60 °F) ÷ 39409.45989391
Derivation from SI units:
- 1 inH₂O (60 °F) ≈ 999.0 kg/m³ × 9.80665 m/s² × 0.0254 m ≈ 248.84 Pa
- 1 kgf/mm² = 9.80665 N ÷ 1 mm² = 9.80665 MPa (exact)
- 1 inH₂O (60 °F) = 248.84 Pa ÷ 9806650 Pa per kgf/mm² = 0.00002537461824374 kgf/mm²
One unit is a measured value, so the factor is approximate. Inch of Water (60 °F) definition: inch of water (60 °F); Kilogram-force per Square Millimetre definition: kilogram-force per square millimetre.
Worked examples
- A reading of 0.5 inH₂O (60 °F) converts to 0.00001268730912 kgf/mm².
0.5 inH₂O (60 °F) × 0.00002537461824 = 0.00001268730912 kgf/mm² - A value of 7 inH₂O (60 °F) is 0.0001776223277 kgf/mm².
7 inH₂O (60 °F) × 0.00002537461824 = 0.0001776223277 kgf/mm²

Where it's used
Inches of Water (60 °F) are used for older US gas-industry and flow-meter references, 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.
