Serving Size Calculator
Divide a measured batch into equal servings. Enter the total food weight or volume and your serving count to calculate each share in US or metric units.
Find the weight or volume of one equal serving from a measured batch of food. Enter the edible amount you actually have and the number of servings you want to make. This is useful for dividing soup, cooked grains or a mixed dish among containers.
How to use this tool
- Weigh or measure the ready-to-serve food, excluding the container.
- Select the matching weight or volume unit.
- Enter a positive whole number of equal servings.
- Read each share in the chosen unit and its metric equivalent.
Formula
amount per serving = measured edible batch amount ÷ number of servings
The calculation divides the measured amount evenly. One pound is exactly 453.59237 grams, and one US fluid ounce is exactly 29.5735295625 millilitres. Weight stays a weight and volume stays a volume.
Example
A batch weighs 1,200 g after cooking. Dividing it into six equal servings gives 1,200 ÷ 6 = 200 g per serving. Each serving represents one sixth of the batch, or approximately 16.6667%. If the batch instead measures 1.5 L and you choose five servings, each share is 0.3 L, or 300 mL.
Frequently asked questions
Is this the serving size for a food label?
No. You choose the number of kitchen servings. FDA label serving sizes follow separate rules and are not recommendations for how much to eat.
Should I enter raw or cooked weight?
Enter the state you intend to divide. For a cooked dish, measure the finished edible yield; water gain or loss during cooking is not predicted.
Can this convert soup millilitres to grams?
No. That requires the actual density. Measuring the total by weight gives portions by weight; measuring by volume gives portions by volume.
What if the servings contain different ingredients?
Equal total weights do not guarantee identical ingredients or nutrients. Stir a suitable mixed dish or distribute its components separately when consistency matters.
