FAQ

What is the conversion factor from g/cm³ to SG?
1 g/cm³ equals 1 SG. To convert, multiply the value in grams per cubic centimetre by 1.
How do I convert 1 g/cm³ to SG?
1 g/cm³ = 1 SG. For any value, multiply by 1.
How do I convert SG back to g/cm³?
Divide by the same factor — or equivalently, multiply by 1. So 1 SG = 1 g/cm³.
When would I need to convert gram per cubic centimetre 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?
Yes. Both g/cm³ and SG are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
