How to Use This Calculator
- Enter the amount, select From unit and To unit.
- Click Calculate for volume conversions between cups, tbsp, tsp, ml, fl oz, and L.
- Use the Weight tab to convert grams, ounces, pounds, and kilograms.
- Use the Temperature tab to convert °F ↔ °C with common baking temperature references.
- Use the Professional tab to convert cups to grams for specific ingredients and scale recipes.
Formula
Volume: Convert to ml first (1 cup = 236.588 ml, 1 tbsp = 14.787 ml, 1 tsp = 4.929 ml), then convert to target unit.
Temperature: °C = (°F − 32) × 5/9 | °F = °C × 9/5 + 32
Example
Example: 2 cups to ml = 2 × 236.588 = 473.2 ml. 350°F to Celsius = (350 − 32) × 5/9 = 177°C. 2 cups flour = 2 × 125g = 250g.
Frequently Asked Questions
- 1 US customary cup = 236.588 ml (often rounded to 237 ml). 1 US legal cup (used in nutrition labeling) = 240 ml exactly. 1 metric cup (Australia, Canada, NZ) = 250 ml exactly. The UK does not use a "cup" measurement officially. For cooking purposes, the difference between 237 ml and 240 ml is negligible (under 1.5%). Related volume conversions: 1 tablespoon = 14.787 ml; 1 teaspoon = 4.929 ml; 1 US fluid ounce = 29.574 ml; 1 cup = 16 tablespoons = 48 teaspoons = 8 fl oz. When converting an American recipe for use in Australia or the UK, use 240 ml per cup — the additional 3–4 ml is insignificant for most recipes except those requiring extreme precision.
- Cups measure volume while grams measure weight, so the conversion depends entirely on the ingredient's density. Key ingredient weights per US cup: all-purpose flour ≈ 125 g; bread flour ≈ 130 g; cake flour ≈ 100 g; granulated sugar ≈ 200 g; packed brown sugar ≈ 220 g; powdered sugar (sifted) ≈ 120 g; butter ≈ 227 g (2 sticks); honey ≈ 340 g; milk ≈ 244 g; water ≈ 237 g; rolled oats ≈ 90 g; cocoa powder ≈ 100 g; rice (uncooked) ≈ 190 g; olive oil ≈ 216 g. These values assume level measurements using the spoon-and-level method. Scooping flour directly from the bag can add 20–30% more weight, which is why weighing ingredients is strongly recommended for baking.
- 350°F = (350 − 32) × 5/9 = 318 × 5/9 = 176.67°C ≈ 177°C. This is one of the most common baking temperatures, used for cakes, cookies, and casseroles. Full oven temperature conversion chart: 250°F = 121°C; 275°F = 135°C; 300°F = 149°C; 325°F = 163°C; 350°F = 177°C; 375°F = 191°C; 400°F = 204°C; 425°F = 218°C; 450°F = 232°C; 475°F = 246°C; 500°F = 260°C. For fan/convection ovens, reduce the temperature by 15–20°C (25–30°F) compared to conventional oven settings, since forced air circulation cooks food more efficiently. Gas mark equivalents: Gas 4 ≈ 350°F = 177°C; Gas 6 ≈ 400°F = 200°C.
- 1 US cup = 16 US tablespoons = 48 teaspoons = 8 US fluid ounces = 236.588 ml. Breaking it down: 1/4 cup = 4 tablespoons; 1/3 cup ≈ 5 tablespoons + 1 teaspoon (5.333 tbsp); 1/2 cup = 8 tablespoons; 2/3 cup ≈ 10 tablespoons + 2 teaspoons; 3/4 cup = 12 tablespoons. International caution: UK tablespoon = 15 ml; Australian tablespoon = 20 ml; US tablespoon = 14.787 ml. So a recipe specifying "3 tablespoons" could mean 44.4 ml (US), 45 ml (UK), or 60 ml (AU) — a 35% difference. When following recipes from different countries, specify the tablespoon origin or convert to ml for precision.
- At elevations above 3,500 feet (1,067 m), lower atmospheric pressure affects baking significantly. Leavening gases (CO2 from baking powder/soda) expand more, causing cakes and breads to rise too quickly then collapse. Adjustments: increase oven temperature by 15–25°F (8–14°C); reduce baking powder/soda by 15–25%; reduce sugar by 1–3 tablespoons per cup; add 2–4 tablespoons more liquid per cup called for; increase flour by 1–2 tablespoons per cup. Water boils at lower temperatures too: at 5,000 ft (1,524 m), water boils at about 203°F (95°C) instead of 212°F (100°C), which affects pasta, rice, and candy making. The higher the altitude, the more significant these adjustments become — Denver (5,280 ft) and Mexico City (7,350 ft) require noticeable recipe changes.
