Liters to kg Converter
Convert volume to mass instantly. Select a substance or enter custom density to find out how many kilograms your liters weigh.
Step 1: Enter Volume
What is liter?
A liter is a unit of volume commonly used for liquids and gases. One liter equals 0.001 cubic meters or 1 cubic decimeter.
Step 2: Choose Substance
Density matters
Density (kg/L) tells how many kilograms one liter of a substance weighs. For example, 1 L of water = 1 kg, but 1 L of olive oil ≈ 0.92 kg.

Conversion Formula
Mass (kg) = Volume (L) × Density (kg/L)
Simply multiply the volume in liters by the density of the substance (in kg per liter) to get the mass in kilograms. For water (density = 1 kg/L), mass equals volume.
