Cups ↔ grams ↔ ounces, adjusted per ingredient density.
🧁 Volume-to-weight depends on how densely you fill the cup (sifted vs spooned flour differs ~20%). We use standard spoon-and-level averages; a kitchen scale always wins.
A US cup holds 240 milliliters of anything, but weight depends on what fills it: one cup of flour weighs about 120 g while one cup of honey weighs 340 g. Converting "1 cup" without naming the ingredient is where recipes break.
Flour measured by scooping the cup straight into the bag can weigh 140 g or more; spooned-and-levelled hits ~120 g; sifted drops toward 114 g. This tool uses spoon-and-level averages, the standard in modern baking references.
Stick butter is sold by weight with tablespoon markings already printed on the wrapper — trust those. One US cup of butter equals exactly 227 g or two sticks.
Baking (bread, cakes, macarons) rewards scale accuracy; soups and stews forgive everything. If a dough feels wrong by feel, trust the dough over the chart.
The Cooking Measurement Converter converts cooking converterfrom one unit to another using the exact internationally defined conversion factors. Type a value, choose your source and target units, and the converted result is shown instantly — no waiting, no page reload.
Manual conversion is error-prone because it means memorizing ratios (how many feet in a meter, how many pints in a liter). This tool removes that friction: the conversion factor is built in, and the math is done to full precision with no rounding until the final displayed number.
Common uses: people reach for this tool when they need to look up a 1 cup flour in grams, butter tablespoons to grams, sugar cup to gram conversion, or recipe unit converter baking.
Browser-based tools like this one have a few real advantages over installed software or manual methods:
The Cooking Measurement Converter is based on the following formula:
weight (g) = volume (ml) × density (g/ml) 1 cup = 236.588 ml 1 tbsp = 14.79 ml = 3 tsp 1 tsp = 4.93 ml 1 cup flour ≈ 125 g 1 cup sugar ≈ 200 g 1 cup butter ≈ 227 g
Variables: cup = US volume cup, 236.588 ml tbsp = tablespoon, 14.79 ml tsp = teaspoon, 4.93 ml g = grams on a kitchen scale oz = ounces, 1 oz = 28.35 g density = packed density of the ingredient in g/ml
Cups measure volume but grams measure weight, so the conversion depends on each ingredient's density: sifted flour sits at about 0.53 g/ml while granulated sugar packs near 0.85 g/ml. That is why a cup of flour weighs roughly 125 g but a cup of sugar 200 g, and dense butter exactly 227 g (two US sticks).
Worked example: A recipe asks for 2 cups of flour: g = 2 × 125 = 250 g You have 340 g of butter: cups = 340 ÷ 227 ≈ 1.5 cups (3 sticks) Small amounts: 1 tbsp = 3 tsp = 14.79 ml
