Convert Inches of Water (60 °F) to Baryes

Formula

Ba = inH₂O (60 °F) × 2488.4

Derivation from SI units:

• 1 inH₂O (60 °F) ≈ 999.0 kg/m³ × 9.80665 m/s² × 0.0254 m ≈ 248.84 Pa
• 1 Ba = 1 dyn/cm² = 10⁻⁵ N ÷ 10⁻⁴ m² = 0.1 Pa
• 1 inH₂O (60 °F) = 248.84 Pa ÷ 0.1 Pa per Ba = 2488.4 Ba

One unit is a measured value, so the factor is approximate. Inch of Water (60 °F) definition: inch of water (60 °F); Barye definition: barye.

Worked examples

1. A reading of 0.5 inH₂O (60 °F) converts to 1244.2 Ba.
   0.5 inH₂O (60 °F) × 2488.4 = 1244.2 Ba
2. A value of 7 inH₂O (60 °F) is 17418.8 Ba.
   7 inH₂O (60 °F) × 2488.4 = 17418.8 Ba

Where it's used

Inches of Water (60 °F) are used for older US gas-industry and flow-meter references, while baryes appear in older physics and acoustics literature. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
