Cooking Measurement Conversion Chart
Your recipe says cups, your scale says grams, and your measuring spoons disagree with both. 2.5 cups = 20 fl oz = 591.47 ml; 1.5 lb = 680.39 g. Look up any kitchen conversion below, then print the reference tables for the fridge.

Cooking weight conversion
Convert ounces, pounds, grams, and kilograms — for recipes that measure by weight.
The 60-second rule
Convert everything through milliliters (volume) or grams (weight): result = amount × (factor of from-unit ÷ factor of to-unit). One cup is 236.588 ml, so 2.5 cups × (236.588 ÷ 29.5735) = 20.00 fl oz, and 2.5 × 236.588 = 591.47 ml. One pound is 453.592 g, so 1.5 × 453.592 = 680.39 g. The factors never change — the confusion comes from mixing US, UK, and Australian spoons.
Worked examples
3 tablespoons to teaspoons and ml: 3 × 14.7868 = 44.3604 ml; 44.3604 ÷ 4.92892 = 9.00 tsp, and the milliliter read is 44.36 ml. Tablespoons are just triple-teaspoons — the one conversion with no rounding.
1 gallon to cups and liters: 3785.41 ÷ 236.588 = 16.00 cups; 3785.41 ÷ 1000 = 3.79 L. Sixteen cups to a gallon is the anchor fact the whole US ladder hangs on.
8 ounces to grams: 8 × 28.3495 = 226.80 g. This is the one bakers should memorize: a stick of butter (8 tbsp / 4 oz) is 113.40 g, and a cup of butter is 226.80 g.

| Converted result | amount × (from-factor ÷ to-factor) | 20.00 fl oz at the defaults — the lookup answer. |
| Milliliter / gram equivalent | amount × from-factor | 591.47 ml (volume) or 680.39 g (weight) — the metric bridge for every conversion. |
| Per-unit rate | from-factor ÷ to-factor | 8.00 fl oz per cup — the reusable ratio for mental math. |
Who uses this
- The baker scaling a recipe: European recipes list grams; US cups are volume — convert flour by weight (1 cup ≈ 120 g, but weigh it) before the cake fails.
- The meal-prepper: "divide the gallon of stock" is 16 cups — the lookup turns vague batch instructions into measurable steps.
- The international cook: UK pints are 568 ml and Australian tablespoons are 20 ml — this page is calibrated to US units and says so plainly.
- The canner/preserver: quart and pint jars meet metric brine recipes constantly — the ml column is the bridge.
Accuracy & limitations
Factors are exact US customary definitions: 1 cup = 236.588 ml, 1 fl oz = 29.5735 ml, 1 avoirdupois oz = 28.3495 g. Honest limits: a UK imperial pint is 568.26 ml (not 473.18), a UK imperial fl oz is 28.41 ml, and an Australian tablespoon is 20 ml (not 14.79) — recipes from those countries need their own factors. Volume-to-weight conversions (cups of flour to grams) are ingredient-specific and not interchangeable: this page converts units, not ingredients. Dry-goods densities vary; a kitchen scale wins every argument a chart can start.

How many cups are in a quart?
4 cups. The ladder runs 1 gallon = 4 quarts = 8 pints = 16 cups, so 1 quart = 2 pints = 4 cups = 32 fl oz = 946.35 ml.
How many tablespoons are in 1/4 cup?
4 tablespoons. A cup holds 16 tbsp, so a quarter cup is 4 tbsp — which is also 2 fl oz or 59.15 ml.
How many grams are in an ounce?
28.35 g (exactly 28.3495 g) for the avoirdupois ounce used in cooking. So 8 oz = 226.80 g and 1 lb (16 oz) = 453.59 g.
Why do US and UK pints differ?
Different historical gallons: the US pint is 473.18 ml (from the US gallon of 3,785.41 ml) while the UK imperial pint is 568.26 ml — about 20% larger. A British recipe's "pint of milk" is not an American pint.
Is a coffee "cup" 8 ounces?
No. Coffee makers measure "cups" at 5–6 fl oz, and a standard mug holds 10–12 fl oz. A true US cup is 8 fl oz (236.59 ml) — for recipes, use a real measuring cup, not your mug.
