g/Ltokg/L

Convert grams per litre (g/L) to kilograms per litre (kg/L).

Factor1 g/L = 0.001 kg/L

Converter

g/L

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

Result
1kg/L

Rendered to 6 significant figures.

Formula

Formula
kg/L = g/L × 0.001

Multiply any value in grams per litre by 0.001 to obtain the value in kilograms per litre.

Worked example

Convert 1000 g/L to kg/L.

  1. 01Start with 1000 g/L.
  2. 02Multiply by the conversion factor: 1000 × 0.001 = 1 kg/L.
Result1000 g/L = 1 kg/L

FAQ

What is the conversion factor from g/L to kg/L?
1 g/L equals 0.001 kg/L. To convert, multiply the value in grams per litre by 0.001.
How do I convert 1 g/L to kg/L?
1 g/L = 0.001 kg/L. For any value, multiply by 0.001.
How do I convert kg/L back to g/L?
Divide by the same factor — or equivalently, multiply by 1000. So 1 kg/L = 1000 g/L.
When would I need to convert gram per litre to kilogram per litre?
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).
