Here is how it works, you buy 50 gallons of oil for $200, you use for a recipe one cup of oil, so you calculate the cost of the cup of oil based on the price you paid for the 50 gallons.

Now what if you have a recipe that requires 10 grams of oil? Ha.. that's weight, and the price for oil you pay is in volume.. so here it comes..... you choose from a predefined list of items (such as of our example oil) and we have already calculated the conversions between weight to volume for you... it includes thousands of ingredients and values are based on USDA info, And all is done...!!! You just add the ingredients to your recipes in any unit of measure you like and you will get the accurate cost!

What if you add an ingredient to your recipe which is your own made ingredient? for example you add an amount of chocolate cream to your cake, How do you calculate this? so we have a solution for this too, you create this cream as a recipe, with all ingredients for it, (example the cocoa and oil and sugars and stuff) and you have now accurate cost of your cream on any unit of measure, Now you convert this recipe (in our case the chocolate cream) as an ingredient... and bingo!!! whenever you choose for a cake any UOM of this cream, you will have accurate cost of it, and the ingredient remains linked to the recipe in case you want to make any changes to it.
