How to Convert Gram per Liter to Kilogram per Liter
- 1 g/L = 0.001 kg/L
- 1 kg/L = 1000 g/L
- Example: convert 15 g/L to kg/L: 15 g/L = 15 × 0.001 kg/L = 0.015 kg/L
Formula
kg/L = g/L ÷ 1000
Derivation from SI units:
- 1 g/L = 10⁻³ kg ÷ 10⁻³ m³ = 1 kg/m³
- 1 kg/L = 1 kg ÷ 10⁻³ m³ = 1000 kg/m³ = 1 g/cm³
- 1 g/L = 1 kg/m³ ÷ 1000 kg/m³ per kg/L = 0.001 kg/L
Both units are defined exactly, so the factor is exact. Gram per Liter definition: gram per liter; Kilogram per Liter definition: kilogram per liter.
Worked examples
- A reading of 1.98 g/L converts to 0.00198 kg/L.
1.98 g/L × 0.001 = 0.00198 kg/L - A value of 35 g/L is 0.035 kg/L.
35 g/L × 0.001 = 0.035 kg/L

Where it's used
Grams per Liter are used for gas densities (CO₂ ≈ 1.98 g/L at 0 °C), while kilograms per liter appear in fuel densities (petrol ≈ 0.74 kg/L, diesel ≈ 0.84 kg/L). Both measure density (mass per unit volume) and mass concentration, so the conversion is a fixed factor.

Frequently asked questions
How many kilograms per liter are in 1 gram per liter?
1 g/L = 0.001 kg/L.
How do I convert grams per liter to kilograms per liter?
Multiply the value in g/L by 0.001, or divide it by 1000. For example, 15 g/L × 0.001 = 0.015 kg/L.
Is the g/L to kg/L conversion exact?
Yes. Both units are defined exactly, and 1 g/L is exactly 0.001 kg/L.
