Rendered to 6 significant figures.

Formula

Formula
SG = kg/L × 1

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

Worked example

Convert 0.85 kg/L to SG.

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

FAQ

What is the conversion factor from kg/L to SG?
1 kg/L equals 1 SG. To convert, multiply the value in kilograms per litre by 1.
How do I convert 1 kg/L to SG?
1 kg/L = 1 SG. For any value, multiply by 1.
How do I convert SG back to kg/L?
Divide by the same factor — or equivalently, multiply by 1. So 1 SG = 1 kg/L.
When would I need to convert kilogram per litre 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).
