kg to Liters Calculator
Convert kilograms to liters using substance density. Since kilograms measure mass and liters measure volume, you need the density of the substance to convert between them. Use this calculator for cooking, chemistry, and everyday conversions.
How to Convert kg to Liters
- Identify the substance and find its density in kg/L (same as g/mL).
- Divide the mass in kilograms by the density.
- The result is the volume in liters.
Formula
Liters = Kilograms ÷ Density (kg/L)
Example Calculation
Convert 2 kg of milk to liters:
Density of whole milk = 1.03 kg/L
Volume = 2 kg ÷ 1.03 kg/L = 1.9417 liters
Substance Density Reference Table
| Substance | Density (kg/L) | 1 kg = Liters |
|---|---|---|
| Water | 1 | 1.0000 L |
| Milk (whole) | 1.03 | 0.9709 L |
| Cooking Oil | 0.92 | 1.0870 L |
| Honey | 1.42 | 0.7042 L |
| Gasoline | 0.75 | 1.3333 L |
Frequently Asked Questions
Is 1 kg always equal to 1 liter?
Only for water at 4°C. Other substances have different densities. For example, 1 kg of honey is only about 0.704 liters, while 1 kg of gasoline is about 1.333 liters.
How do I convert kg to liters for cooking oil?
Cooking oil has a density of approximately 0.92 kg/L. Divide the mass by 0.92. For example, 1 kg of cooking oil = 1 ÷ 0.92 = 1.087 liters.
Why can't I directly convert kg to liters?
Kilograms measure mass while liters measure volume. Different substances occupy different volumes for the same mass because they have different densities.
What is the density of water in kg/L?
Water has a density of approximately 1.0 kg/L (or 1000 kg/m³) at 4°C. At room temperature (20°C), it is about 0.998 kg/L.
How many liters is 5 kg of milk?
Whole milk has a density of about 1.03 kg/L. So 5 kg ÷ 1.03 = approximately 4.854 liters of milk.
