Factor1 SG = 1000 kg/m³

Converter

SG

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

Result
850kg/m³

Rendered to 6 significant figures.

Formula

Formula
kg/m³ = SG × 1000

Multiply any value in specific gravity (water) by 1000 to obtain the value in kilograms per cubic metre.

Worked example

Convert 0.85 SG to kg/m³.

  1. 01Start with 0.85 SG.
  2. 02Multiply by the conversion factor: 0.85 × 1000 = 850 kg/m³.
Result0.85 SG = 850 kg/m³

FAQ

What is the conversion factor from SG to kg/m³?
1 SG equals 1000 kg/m³. To convert, multiply the value in specific gravity (water) by 1000.
How do I convert 1 SG to kg/m³?
1 SG = 1000 kg/m³. For any value, multiply by 1000.
How do I convert kg/m³ back to SG?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 kg/m³ = 0.001 SG.
When would I need to convert specific gravity (water) to kilogram per cubic metre?
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).
