About the Cooking Conversion Calculator
American recipes measure most ingredients by volume, while European and professional recipes weigh them. Because a cup of flour weighs about 125 g but a cup of honey weighs about 340 g, you cannot convert cups to grams without knowing what is in the cup. This calculator uses a typical density for each ingredient so the conversion is realistic.
Flour values assume it is spooned into the cup and leveled; scooping straight from the bag packs in up to 20% more. For baking, weighing on a kitchen scale is the most reliable method. Note that "ounces" here are ounces of weight, not fluid ounces.
Formula
Volume and weight are linked by the ingredient's density (how many grams fit in one cup):
grams = cups × grams per cup
cups = grams ÷ grams per cup
Spoon and liquid measures are converted through cups first: 1 cup = 16 tbsp = 48 tsp = 8 fl oz = 236.6 mL. Weights use 1 oz = 28.35 g and 1 lb = 453.6 g.
Example calculation
Using the default values:
- Amount = 2
- From = cups
- Ingredient = All-purpose flour (spooned & leveled)
- To = grams
the calculator returns:
- Result: 250 g
Frequently asked questions
How many grams is 2 cups of all-purpose flour?
About 250 grams when the flour is spooned and leveled (125 g per cup).
Is a fluid ounce the same as an ounce?
No. A fluid ounce measures volume (29.6 mL), while an ounce measures weight (28.35 g). They only match closely for water and similar liquids.
Why do different websites give different grams per cup?
Ingredients settle and pack differently, and measuring methods vary. Values within about 5% of each other are all reasonable; a scale removes the guesswork.
