## How to Convert Liters to Kilograms: A Guide

It's impossible to directly convert liters to kilograms because they measure different things. **Liters (L)** measure **volume**, which is the amount of space a substance occupies. **Kilograms (kg)** measure **mass**, which is the amount of matter in a substance.

To convert liters to kilograms, you need to know the **density** of the substance you're measuring. Density is the mass per unit volume. Here's the formula:

**Density = Mass / Volume**

**To convert liters to kilograms, follow these steps:**

**Identify the substance:**You need to know what substance you're working with (e.g., water, oil, mercury).**Find the density of the substance:**You can find the density of common substances online or in a reference book.**Convert the volume to cubic meters:**1 liter is equal to 0.001 cubic meters (m³).**Multiply the density by the volume:**This will give you the mass in kilograms.

**Here's an example:**

Let's say you have 0.8 liters of water. The density of water is approximately 1 kg/L.

**Volume:**0.8 L**Density:**1 kg/L**Mass:**0.8 L * 1 kg/L =**0.8 kg**

**Therefore, 0.8 liters of water weighs approximately 0.8 kilograms.**

**Important Notes:**

- The density of substances can vary depending on factors like temperature and pressure.
- This conversion only applies to pure substances. Mixtures will have different densities.

**Remember:** Always use the appropriate units and be mindful of the density of the substance when converting liters to kilograms.
