Step-by-Step Mathematical Explanation
- Convert volume to milliliters: 1 cup × 236.588237 = 236.5882 ml.
- Apply the density of all-purpose flour (0.5283 g/ml): 236.5882 ml × 0.5283 = 125 g.
Cup & Spoon Sizes
Quick Answer & Key Kitchen Conversions
Direct Answer: 1 US cup equals 236.59 ml, 16 tablespoons or 48 teaspoons. In grams it depends on the ingredient: 1 cup of all-purpose flour ≈ 125 g, granulated sugar ≈ 200 g, butter ≈ 227 g and water ≈ 237 g. To convert ml to cups, divide by 236.59 for US cups or by 250 for metric cups. 1 US gallon = 3.785 l.
Understanding Kitchen Measurements & Conversion Math
Cups and spoons measure volume, while scales measure weight. Converting between the two needs the ingredient's density — how many grams fit in one milliliter. Flour is light and airy (about 0.53 g/ml), honey is heavy (about 1.44 g/ml), so the same cup can hold 125 g or 340 g.
1. Cups to Grams (cups → g)
Convert the cups to milliliters, then multiply by the ingredient's density. Most bakers simply use a grams-per-cup value for each ingredient:
Example: 2 cups of all-purpose flour × 125 g = 250 g.
2. Milliliters to Cups (ml → cups)
Volume-to-volume conversions don't need a density — just divide by the cup size of the recipe's measuring system:
Example: 500 ml ÷ 236.59 = 2.11 US cups (exactly 2 metric cups).
Spoon & Level — or Better, Weigh It
Scooping flour straight from the bag packs it down and can add 20–25% more flour than the recipe intends. Spoon it into the cup and level it off, or use a kitchen scale and the gram values below for consistent results.
½ cup = 8 tbsp; ¼ cup = 4 tbsp; ⅓ cup = 5 tbsp + 1 tsp; 1 tbsp = 3 tsp.
Common Ingredient Weights per US Cup
| Ingredient | Grams per Cup | Ounces per Cup | Note |
|---|---|---|---|
| All-Purpose Flour | 125 g | 4.4 oz | Spooned and leveled |
| Granulated Sugar | 200 g | 7.1 oz | White or caster sugar |
| Brown Sugar | 213 g | 7.5 oz | Firmly packed |
| Butter | 227 g | 8.0 oz | Two US sticks |
| Water | 237 g | 8.3 oz | 1 g per ml reference |
| Honey | 340 g | 12.0 oz | Dense syrup, ~1.44 g/ml |
| White Rice (uncooked) | 185 g | 6.5 oz | Long-grain, dry |
| Rolled Oats | 90 g | 3.2 oz | Old-fashioned, dry |
Frequently Asked Questions
How many grams are in a cup?
It depends on the ingredient. One US cup holds about 237 g of water, 125 g of all-purpose flour, 200 g of granulated sugar, 227 g of butter and 340 g of honey. Select the ingredient in the converter for an exact value.
Why doesn't a cup of flour weigh the same as a cup of sugar?
Cups measure volume, not weight. Sugar crystals pack tightly (about 0.85 g/ml) while flour is full of air (about 0.53 g/ml), so a cup of sugar weighs roughly 60% more than a cup of flour.
What is the difference between US, UK and metric cups?
A US customary cup is 236.59 ml, a metric cup (Australia, New Zealand, Canada) is 250 ml, and the traditional British imperial cup is 284.13 ml (half an imperial pint). Most modern UK recipes use grams or the 250 ml metric cup.
How many tablespoons are in a cup?
A US cup contains 16 tablespoons (48 teaspoons). A 250 ml metric cup holds about 16.7 standard 15 ml tablespoons.
How many liters are in a gallon?
One US gallon is exactly 3.785411784 liters. The UK imperial gallon is larger: exactly 4.54609 liters.
