L to kg Converter

Liters to Kilograms Converter is a helpful tool for converting the volume of ingredients from liters to an equivalent weight in kilograms. This tool also provides the density of the selected substance to ensure the accuracy and efficiency of the conversion.

How to Convert Liters to Kg?

Liter (ℓ) is a metric unit of volume whereas kilogram (kg) is the base unit of mass. Converting liters to kg is not simple because these units measure different quantities. An additional physical quantity is required to perform this conversion. Density plays a pivotal role in facilitating the conversion of liters to kilograms or any other unit of mass.

You can convert liters to kilograms by multiplying the volume in liters with the density of the substance in kilograms per liter.

Note: The density of a substance can vary depending on factors such as temperature and pressure. It is important to make sure you are using the correct density value when making conversions.

Formula to Convert Liters to Kilograms

Use the following formula to convert liters to kilograms.

Kilograms = Liters × Density

To apply this formula, we need to know the density. The density of the substance or liquid is the ratio of the mass to volume and it measures how much mass fits within a certain volume.

While converting the litter in kg, it is important to note that the density must be expressed in kilograms per liter (kg/L).


Convert 1 liter water to kg whose density is 1 kg/L.

Kilograms = 1L x 1 kg/L = 1 kg

Why do we need to Convert Liters to Kilograms?

Here are some examples of real-world situations where converting liters to kilograms is necessary.

Cooking and baking

Liters are often used for liquids like water, milk, or oil, and kilograms for dry ingredients like flour and sugar. Converting these volumes to kilograms is essential for accurate ingredient proportions especially when dealing with recipes that require precise measurements.

For example, a cake recipe calls for 2 liters of milk and 500 grams of flour. You need to convert the volume of milk from liters to kilograms to ensure that the cake is made with the correct balance of liquid and dry ingredients.

Shopping and purchasing

Suppose you are at the grocery store and trying to compare the cost of two different cooking oil brands. Brand A is sold in a 2-liter bottle for $5 while Brand B is sold in a 2.5-kilogram container for $7. It is helpful to convert the liters to kilograms to compare the cost of these two options.

Shipping and Transportation

Converting liters to kilograms ensures vehicles stay within weight limits for safety and compliance. For example, a tanker truck carrying 1000 liters of chemicals must convert to kilograms to meet regulatory weight restrictions and ensure a safe journey.


Our liter to kg converter can convert liters to kilograms in a matter of seconds. If you prefer manual calculations, there is no issue. Here are some examples to help you learn how to perform the conversion.

Example 1:

Convert 10 liters of milk into a kilogram.


Step 1: Look up the density of milk. The density of milk can vary slightly depending on factors such as fat content but a typical value is around 1.03 kg/L.

Step 2: Use the formula.

Kilograms = Liters × Density

Step 3: Perform Calculation.

Kilograms = 1.03 kg/L x 10 L

Kilograms = 10.3 kg

Thus, 10 liters of milk weigh 10.3 kilograms.

Example 2:

How many kilograms are there in 15 liters of olive oil?


Step 1: Identify the density of olive oil. You can also find density using the above calculator.

The density of olive oil is around 0.92 kg/L.

Step 2: Apply the formula to convert the liter into a kilogram.

Kilograms = Liters × Density

Step 3: Perform Calculation.

Kilograms = 0.92 kg/L x 15 L

Kilograms = 13.8 kg

Thus, 15 liters of olive oil weigh approximately 13.8 kilograms.
