How to Convert Kilograms to Liters

The calculator converts mass to volume by using density. Internally it converts your mass to kilograms, density to kg/m³ (or uses g/mL presets), computes volume in m³, and then displays results in the volume unit you choose.

Kilograms to Liters Formula

Volume (L) = Mass (kg) ÷ Density (kg/L). If density is provided in g/mL: kg/L is the same numeric value (1 g/mL = 1 kg/L).

When to Convert Kilograms to Liters

Convert when you need to know how much space a mass of liquid will occupy (cooking, lab work, shipping liquids, or filling containers). Remember density varies with temperature and composition.

What Is a Kilogram?

A kilogram is the SI unit of mass, defined by the international prototype of the kilogram standard. It measures the quantity of matter.

What Is a Liter?

A liter is a unit of volume equal to 1 cubic decimeter (0.001 m³). For water at ~4 °C, 1 L ≈ 1 kg due to density ~1 kg/L.

Kilogram to Liter Conversion Table (examples)

  • 1 kg of water ≈ 1 L
  • 2 kg of water ≈ 2 L
  • 5 kg of cooking oil (0.92 g/mL) ≈ 5 ÷ 0.92 ≈ 5.435 L
  • 2 kg of milk (1.035 g/mL) ≈ 1.932 L

FAQs

How many litres is 1 kg?
It depends on density. For pure water ~1 kg = 1 L. For other liquids divide mass by density (kg/L).
What is 5 kg in litres?
For water 5 kg = 5 L. For oil (~0.92 g/mL) 5 ÷ 0.92 ≈ 5.435 L. Use the density selector or enter a custom density.
How to convert kg into L?
Volume (L) = Mass (kg) ÷ Density (kg/L). If density is in g/mL, the numeric value equals kg/L.
What is 2 kg in litres?
For water ≈ 2 L. For milk (~1.035 kg/L) 2 ÷ 1.035 ≈ 1.93 L.
