Calculate serving count, total food weight or weight per serving from the other two quantities. The whole-servings option also shows the food weight left over.

Use the serving weight from the food label or your recipe. A label serving is not a recommended amount to eat.

Grams To Servings Formula

The following formula is used to calculate the number of servings from the weight in grams of a food item.

S = G / GS

Variables:

  • S is the number of servings
  • G is the weight of the food item in grams
  • GS is the weight in grams of one serving of the food item

To calculate the number of servings, divide the weight of the food item in grams by the weight in grams of one serving of the food item.

What is Grams To Servings?

Grams to servings is a conversion method used to determine the number of servings in a specific weight (grams) of a food item. This is often used in nutritional calculations where it’s important to know the serving size to accurately determine the amount of calories, fats, proteins, and other nutrients consumed. Use the serving weight stated for the particular food or recipe. Density is only needed if a separate volume-to-mass conversion is required. A label serving is not a recommendation of how much to eat; see the FDA serving-size explanation.

How to Calculate Grams To Servings?

The following steps outline how to calculate the Grams To Servings using the formula: S = G / GS


  1. First, determine the weight of the food item in grams (G).
  2. Next, determine the weight in grams of one serving of the food item (GS).
  3. Next, gather the formula from above: S = G / GS.
  4. Finally, calculate the number of servings (S).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

weight of the food item in grams (G) = 500

Weight per serving GS = 50g. The serving count is500 /50 =10 servings.
