FAQ

What is the conversion factor from oz/in³ to SG?
1 oz/in³ equals 1.729994 SG. To convert, multiply the value in ounces per cubic inch by 1.729994.
How do I convert 1 oz/in³ to SG?
1 oz/in³ = 1.72999 SG. For any value, multiply by 1.729994.
How do I convert SG back to oz/in³?
Divide by the same factor — or equivalently, multiply by 0.5780367. So 1 SG = 0.578037 oz/in³.
When would I need to convert ounce per cubic inch to specific gravity (water)?
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).
