FAQ

What is the conversion factor from SG to oz/in³?
1 SG equals 0.5780367 oz/in³. To convert, multiply the value in specific gravity (water) by 0.5780367.
How do I convert 1 SG to oz/in³?
1 SG = 0.578037 oz/in³. For any value, multiply by 0.5780367.
How do I convert oz/in³ back to SG?
Divide by the same factor — or equivalently, multiply by 1.729994. So 1 oz/in³ = 1.72999 SG.
When would I need to convert specific gravity (water) to ounce per cubic inch?
Density conversions are critical for fluid property datasheets, hydraulic head calculations, and reconciling lab measurements (often g/cm³) with process simulator inputs (kg/m³).
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
