# Convert purchase format for products to a base unit (Kg, L or Unit)

## Why?

📦 Converting **purchase formats** (boxes, bottles, etc.) **to a base unit of measure** (kilograms, liters, etc.) is essential.

🚚 When working with different suppliers and products, it is common for **purchase formats to vary**, which can create confusion and errors in cost control, recipes, and inventory.

🍔 Converting all purchase formats to a base unit makes it possible to compare prices more accurately, define the amount of product used in recipes, and control production costs.

### Convert purchase format to base unit (Kg, L, Units):

1. Select the **product** you want to configure and, in the top-right option, click **"configure"**

* **Unit** → Products sold or used in dishes by **whole units.** Eggs, burgers, soda cans, wine bottles, etc.
* **Kg** or **g** → Products consumed by weight or mass. Pasta, fresh tuna, flour, vegetables, etc.
* **L** or **ml** → Liquid products consumed in different quantities. Sauces and broths, beer keg, wine by the glass, etc.

4. Enter **the equivalence** between the purchase format and the base unit (for example: 1 Box = 5 Kg)
