Cooking Measurement Conversions
Convert between US customary, metric, and imperial measurements used in recipes. US recipes use volume (cups, tablespoons); most international recipes use weight (grams).
Volume Conversions
- 1 cup = 16 tbsp = 48 tsp = 8 fl oz = 237 ml
- 1 tbsp = 3 tsp = 0.5 fl oz = 15 ml
- 1 pint = 2 cups = 473 ml
- 1 quart = 4 cups = 946 ml
- 1 gallon = 16 cups = 4 quarts = 3.8 L
Weight Conversions
- 1 ounce = 28.35 grams
- 1 pound = 16 oz = 454 grams
- 1 kilogram = 2.2 pounds = 35.27 oz
Common Oven Temperatures
- 250°F = 120°C (Low — slow roasting)
- 325°F = 163°C (Moderate low — casseroles)
- 350°F = 175°C (Moderate — most baking)
- 375°F = 190°C (Moderate high — cookies)
- 400°F = 200°C (Hot — roasting vegetables)
- 425°F = 218°C (Hot — pizza, bread)
- 450°F = 230°C (Very hot — searing)
- 500°F = 260°C (Broil)
Temperature formula: °C = (°F − 32) × 5/9 and °F = (°C × 9/5) + 32
Volume vs Weight: Why It Matters
A cup of flour can weigh 120-160 grams depending on how you scoop it — that's up to a 33% difference. Volume works fine for liquids and casual cooking, but weight is more reliable for baking. Key examples:
- 1 cup all-purpose flour: 120g (spooned) to 160g (packed)
- 1 cup granulated sugar: 200g
- 1 cup brown sugar: 220g (packed)
- 1 cup butter: 227g (2 sticks)
- 1 cup water/milk: 237g
- 1 cup honey: 340g
Common Ingredient Equivalents
- 1 stick butter: ½ cup = 8 tbsp = 4 oz = 113g
- 1 large egg: about 50g (3 tbsp liquid)
- 1 clove garlic: ½ tsp minced
- Juice of 1 lemon: about 3 tbsp
- Juice of 1 lime: about 2 tbsp
- 1 medium onion, diced: about 1 cup
