Recipe Converter – Scale Recipes and Convert Cups
You found a lovely recipe, but it serves four and eight people are coming for dinner. Or it serves twelve, and tonight it is just the two of you.
Recipe Converter
Cup weights used: flour 120 g, granulated sugar 200 g, brown sugar 220 g, butter 227 g, milk / water 240 g, cocoa powder 100 g, honey 340 g, rolled oats 90 g.
The secret is simple maths, not guesswork.
Every ingredient scales by the same factor, and every cup weighs a fixed amount in grams. Once you know the factor, the whole recipe follows it.
This free recipe converter does both jobs at once. It scales any recipe up or down by servings, and it converts cups to grams for eight common ingredients, so your baking turns out right every time.
Scaling by feel is where recipes go wrong. A pinch more here and a splash less there soon adds up, and a cake that should be light turns dense.
The converter also lists the weight of one cup for each ingredient, so you can see at a glance why a cup of butter and a cup of oats are not the same at all.
How to Use This Calculator
Example
Let us scale a cake recipe from 4 servings to 8 servings.
The recipe calls for 2 cups of all-purpose flour.
First the scale factor: 8 divided by 4 is 2.
So every amount doubles. Two cups of flour becomes 4 cups.
One cup of flour weighs 120 grams, so 4 cups is 4 times 120, which is 480 grams.
The same rule works in reverse. If a recipe lists 240 grams of flour, divide by 120, and you get 2 cups.
Try the same recipe for two people instead. The factor is 2 divided by 4, which is 0.5, so 2 cups of flour becomes 1 cup, or 120 grams.
Sugar scales the same way. If the recipe lists 1 cup of granulated sugar, doubling gives 2 cups, which is 400 grams, since one cup weighs 200 grams.
Scale every ingredient by the same factor, and the flavour stays just as the recipe intended.
The Bottom Line
A recipe is a ratio, not a fixed list.
When every ingredient scales by the same factor, the flavour, texture, and baking time stay close to the original.
Cups measure volume, and grams measure weight, so converting between them needs the weight of each ingredient. That is why the same cup of honey weighs far more than a cup of oats.
Use this converter before you shop or start cooking, and keep it open while you measure. Your recipes will come out right, whatever the crowd.
Save the factor, not the guesswork, and every recipe becomes one you can trust at any table size.
Frequently Asked Questions
How do I scale a recipe up or down?
Divide the servings you want by the servings the recipe makes. That number is the scale factor. Multiply every ingredient amount by it, and the recipe keeps its balance.
How many grams are in a cup of flour?
One cup of all-purpose flour weighs 120 grams. So 2 cups is 240 grams, and half a cup is 60 grams. Weigh flour for the most accurate baking.
Why do cups and grams not match for every ingredient?
A cup measures volume, while a gram measures weight. Dense ingredients weigh more per cup than light ones, so honey weighs far more than oats in the same cup.
Can I convert grams back to cups?
Yes. Divide the grams by the weight of one cup of that ingredient. For flour, 240 grams divided by 120 grams per cup gives 2 cups.
What if my ingredient is not in the list?
Use the scale factor on its own, without converting. Multiply the amount by the factor, and keep the original unit. The result stays correct for any ingredient.
Should I scale baking time too?
No, not by the same factor. A doubled cake may need a little more time, so check it early and test with a skewer before taking it out.
