But what is a unit? A unit is the format in which a product (ingredient or recipe) will be used in a given context. Purchases, production, and sale are all contexts in which an ingredient or a recipe will potentially be used.

These can be units:

• of weight (gram, kilogram,...)
• volume (liter, deciliter,...)
• or pieces, which are completely customizable and flexible units (eg: 1 crate of 10 kg of apples, 1 box of 20 crates of 250 g of raspberries, etc.)
• More..

For example:
we buy the cream in the jar but we use it by the gram in a recipe. We buy soda cans in boxes of 24 but we sell them individually.

Unit management allows:

• to accurately calculate the costs and margins of products
• to manipulate recipes by automatically factoring quantities to produce a given number of servings
• to simply convert a product need into the number of packaging lots available for purchase
