公式

## Specific Gravity **Specific Gravity = Density of Substance / Density of Water** Since water density is 1 g/cm³ (or 1000 kg/m³ at 4°C), specific gravity is numerically equal to density in g/cm³. ### Quick Conversions - **kg/m³** = SG x 1,000 - **g/cm³** = SG x 1 - **lb/ft³** = SG x 62.428 - **lb/gal** = SG x 8.345

计算示例

Convert SG 1.025 (seawater).

  1. 01kg/m³ = 1.025 x 1000 = 1025
  2. 02g/cm³ = 1.025
  3. 03lb/ft³ = 1.025 x 62.428 = 63.99
  4. 04lb/gal = 1.025 x 8.345 = 8.554
