## Cargo Density Calculator: worked example

Example values: Weight 24,000 kg, Volume 30 m³. With these values the results are:

| Density | 800.0 kg/m³ |

| Density | 0.800 t/m³ |

| Stowage factor | 1.250 m³/t |

### How to use: Cargo Density Calculator

- Enter your own values: Weight, Volume.

- Results are calculated as you type: Density, Density, Stowage factor, Freight class.

- Check every step of the calculation in the formulas below.

## How is it calculated?

- **Density** = [Weight] ÷ [Volume]

- **Density** = [Weight] ÷ [Volume] ÷ 1,000

- **Stowage factor** = [Volume] ÷ ([Weight] ÷ 1,000)
