## Understanding Liters and Kilograms

Liters (L) and kilograms (kg) are units of measurement used for different physical quantities.

**Liters**measure**volume**, which is the amount of space a substance occupies.**Kilograms**measure**mass**, which is the amount of matter in an object.

You cannot directly convert liters to kilograms because they measure different things. To convert between liters and kilograms, you need to know the **density** of the substance.

## Density: The Key to Conversion

Density is a measure of how much mass is contained in a given volume. It is calculated by dividing the mass of a substance by its volume.

**Density = Mass / Volume**

**Example:**

Let's say you have 0.9 liters of water. The density of water is approximately 1 kg/L.

To find the mass of the water in kilograms, you can use the following formula:

**Mass = Density x Volume**

**Mass = 1 kg/L x 0.9 L = 0.9 kg**

Therefore, 0.9 liters of water weighs **0.9 kilograms**.

## Important Note:

The density of substances can vary depending on factors such as temperature and pressure. For example, the density of water at 4°C is slightly higher than at room temperature.

To accurately convert between liters and kilograms, you need to know the density of the specific substance at the given temperature and pressure.
