Convert kgf/cm² to Inches of Water (60 °F)

Formula

inH₂O (60 °F) = kgf/cm² × 394.0945989391

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 inH₂O (60 °F) ≈ 999.0 kg/m³ × 9.80665 m/s² × 0.0254 m ≈ 248.84 Pa
• 1 kgf/cm² = 98066.5 Pa ÷ 248.84 Pa per inH₂O (60 °F) = 394.0945989391 inH₂O (60 °F)

One unit is a measured value, so the factor is approximate. Kilogram-force per Square Centimetre definition: kilogram-force per square centimetre; Inch of Water (60 °F) definition: inch of water (60 °F).

Worked examples

1. A reading of 7 kgf/cm² converts to 2758.662193 inH₂O (60 °F).
   7 kgf/cm² × 394.0945989 = 2758.662193 inH₂O (60 °F)
2. A value of 100 kgf/cm² is 39409.45989 inH₂O (60 °F).
   100 kgf/cm² × 394.0945989 = 39409.45989 inH₂O (60 °F)

Where it's used

Kilograms-force per Square Centimetre are used for pressure gauges in India, Japan and Latin America, while inches of water (60 °F) appear in older US gas-industry and flow-meter references. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
