About Cooking Calculations
Recipe Scaling:
When scaling recipes, the calculator multiplies all ingredient amounts by the ratio of desired servings to original servings. For example, doubling a recipe (4 to 8 servings) multiplies all ingredients by 2.
Measurement Conversions:
- Volume: 1 cup = 16 tablespoons = 48 teaspoons = 240 ml
- Weight: 1 pound = 16 ounces = 453.6 grams
- These are approximate - ingredient density affects exact conversions
Temperature Conversions:
- Fahrenheit to Celsius: (°F - 32) × 5/9
- Celsius to Fahrenheit: (°C × 9/5) + 32
- Gas marks are approximate temperature ranges
Cooking Time Adjustments:
The calculator uses an approximate formula where time is inversely proportional to temperature difference. However, actual cooking times depend on many factors including food thickness, moisture content, and altitude.
Important Notes:
- Always monitor food while cooking, especially when adjusting recipes
- Use a food thermometer to ensure proper doneness
- Some recipes don't scale linearly (especially baking)
- Seasoning amounts may need adjustment when scaling
- Cooking times are estimates - always check for doneness

Cooking Calculator Guide
Use this cooking calculator to scale recipes, convert common kitchen measurements, and estimate adjusted cooking time when temperature or serving size changes. It is designed for practical kitchen planning rather than replacing the recipe's instructions.
Recipe scaling tips
Multiply ingredient quantities by the new serving ratio, then review ingredients such as salt, spices, yeast, and raising agents carefully. Pan size, thickness, and oven type can change the final cooking time.
Check the result while cooking
Use internal temperature, texture, color, and food-safety guidance to decide when food is ready. The calculator provides an estimate, so avoid relying on time alone for meat, poultry, eggs, and other temperature-sensitive foods.
