Factor1 SG = 1 g/mL

Converter

SG

Accepts numbers or expressions, e.g. 150 + 14.7

Result
0.85g/mL

Rendered to 6 significant figures.

Formula

Formula
g/mL = SG × 1

Multiply any value in specific gravity (water) by 1 to obtain the value in grams per millilitre.

Worked example

Convert 0.85 SG to g/mL.

  1. 01Start with 0.85 SG.
  2. 02Multiply by the conversion factor: 0.85 × 1 = 0.85 g/mL.
Result0.85 SG = 0.85 g/mL

FAQ

What is the conversion factor from SG to g/mL?
1 SG equals 1 g/mL. To convert, multiply the value in specific gravity (water) by 1.
How do I convert 1 SG to g/mL?
1 SG = 1 g/mL. For any value, multiply by 1.
How do I convert g/mL back to SG?
Divide by the same factor — or equivalently, multiply by 1. So 1 g/mL = 1 SG.
When would I need to convert specific gravity (water) to gram per millilitre?
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).
