What it does

A cup of flour weighs nearly half a cup of honey because volume ignores density. Each ingredient needs its own grams per cup figure, which this converter pairs with the cup count for exact weights.

The tool above takes cups with the ingredient. It returns grams, ounces, and tablespoons together.

Flour proves the point hardest: scooped cups pack to 150 grams while spooned cups settle near 120. Recipes tested by weight repeat; recipes tested by scoops gamble.

Liquids convert cleanly near 236 grams per cup since water defines the scale. Milk, juice, and oil sit within sips of it, while honey and syrup run far denser.

How to use

  1. Enter the cup count including fractions.
  2. Pick the exact ingredient.
  3. Weigh the grams on a kitchen scale.
  4. Use tablespoons only for small amounts.

Formula

Grams = cups x grams per cup. Ounces = grams / 28.3495. Tbsp = cups x 16.
g per cup
Ingredient density: flour 120 through butter 227.
28.3495
Grams per ounce for the imperial readout.
x 16
Tablespoons per cup, volume only.

Sifted versus scooped flour shifts the per cup figure most. Professional recipes state the method or the weight to remove doubt.

Worked example

Example: 2 cups flour

Two cups of all purpose flour.

  1. Grams: 2 x 120 = 240 g.
  2. Ounces: 240 / 28.3495 = 8.47 oz.
  3. Tablespoons: 2 x 16 = 32 tbsp.
  4. Scale check: 240 g reads 8.47 oz on either unit.

Limits

  • US cups assumed. Metric and imperial cups differ slightly.
  • Brand grinds and moisture shift flour most.
  • Packed versus loose changes brown sugar.
  • Chopped versus whole changes chunky ingredients.

Common mistakes

  • Scooping flour with the cup, packing twenty percent extra.
  • Swapping ingredients at equal cups.
  • Reading fluid ounces as weight ounces.
  • Halving with odd cup fractions instead of grams.
  • Trusting cup lines on liquid jugs for dry goods.

Try it yourself

Quick checks. Answers sit tucked under each question.

1.5 cups sugar in grams?

1.5 x 200 = 300 g.

0.5 cup butter in ounces?

113.5 g / 28.3495 = 4 oz, which is one stick.

Questions

How many grams in a cup of flour?

About 120 spooned and leveled. Scooped cups reach 150.

Why do recipes use weight?

Repeatability. Grams ignore packing, humidity, and scooping style.

Cups or scale: which is better?

Scales for baking, cups for rough cooking. Precision matters in doughs.

How many cups in 500 g flour?

About 4.17 cups at 120 g each.

Is a US cup 250 ml?

No, 236.588 ml. The 250 ml cup is metric, used in Commonwealth recipes.

Butter sticks to cups?

One US stick is half a cup: 113.5 g or 4 oz.
