How to convert liters to kilograms?

A liter (L) is a unit of volume in the metric system, while a kilogram (kg) is a unit of mass. You cannot directly convert liters to kilograms without knowing the substance, because the relationship depends on density (how much mass fits into a given volume).

The formula to convert liters to kilograms is:

Kilograms = Liters × Density

where density must be in kg/L (kilograms per liter).

For water at standard conditions (around 4°C), the density is exactly 1 kg/L, so 1 liter of water = 1 kilogram. For other substances, the density varies.

Popular examples with approximate densities:

  • Water ≈ 1 kg/L → 1 L = 1 kg
  • Milk ≈ 1.03 kg/L → 1 L ≈ 1.03 kg
  • Vegetable/Cooking oil ≈ 0.92 kg/L → 1 L ≈ 0.92 kg
  • Gasoline ≈ 0.74 kg/L → 1 L ≈ 0.74 kg
  • Mercury ≈ 13.6 kg/L → 1 L ≈ 13.6 kg

Quick examples:

  • 5 liters of water = 5 × 1 = 5 kg
  • 2 liters of cooking oil = 2 × 0.92 = 1.84 kg
  • 10 liters of milk = 10 × 1.03 = 10.3 kg
  • 1 liter of gasoline = 1 × 0.74 ≈ 0.74 kg

 

Liter

A liter (L) is a unit of volume in the metric system. Liters are mainly used in scientific, technical, and everyday applications, such as measuring liquids like water, oil, or juice.

To convert liters to other units of volume, you can use the following conversions:

  • 1 L = 33.814 fluid ounces (fl oz)
  • 1 L = 1.05669 quarts (qt)
  • 1 L = 0.264172 gallons (gal)
  • 1 L = 1000 milliliters (mL)
  • 1 L = 1000000 microliters (μL)

 

Kilogram

A kilogram (kg) is the base unit of mass in the International System of Units (SI). Kilograms are primarily used in scientific, technical, commercial, and everyday applications worldwide for measuring mass, such as body weight, food items like produce or packaged goods, and industrial materials.

To convert kilograms to other common units of mass, you can use the following conversions (approximate values where noted for practicality):

  • 1 kg = 1000 grams (g)
  • 1 kg = 1,000,000 milligrams (mg)
  • 1 kg ≈ 2.20462 pounds (lb)
  • 1 kg ≈ 35.274 ounces (oz)
  • 1 kg = 0.001 metric tons (t) or tonnes
