Convert and scale serving sizes for recipes, portions, ingredients, and nutrition. Use this converter to change a recipe from one number of servings to another, resize ingredient amounts, estimate calories per serving, and adjust meal prep portions.
Scale factor:
new servings ÷ original servings
New ingredient amount:
original amount × scale factor
Calories per original serving:
total calories ÷ original servings
Calories per new serving:
total calories ÷ new servings
Serving size conversions are useful for meal prep, family dinners, party food, baking, recipe scaling, nutrition tracking, portion control, leftovers, grocery planning, and changing recipes from small batches to larger batches.
Use this converter as a practical guide. Baking recipes may need extra care when scaling very large or very small batches.
Your result shows how much to multiply the recipe by and what the new ingredient amount should be. It also estimates the amount per serving, calories per serving, and the difference between the original and new recipe size.
Serving conversions are simple for most ingredients, but salt, spices, yeast, baking powder, baking soda, thickening agents, and cooking time may not always scale perfectly.
Divide 6 by 4 to get 1.5. Multiply each ingredient by 1.5.
Use a scale factor of 0.5 and multiply each ingredient amount by 0.5.
Use a scale factor of 2 and multiply each ingredient amount by 2.
Divide the total recipe calories by the number of servings.
Sometimes. Larger batches, deeper pans, and thicker food may need more cooking time, while smaller batches may cook faster.
