About This Tool

### Scale Recipes Instantly Found a recipe that serves 4 but you're hosting 12? Or maybe you're cooking for just one? Doing the fraction math in your head (1/3 cup * 2.5?) is a recipe for disaster. **Recipe Scaler** automatically parses ingredients and scales them up or down. ### How It Works 1. **Paste Recipe**: Copy the ingredient list from any website. 2. **Choose Scale**: Select 2x (Double), 0.5x (Half), or a custom multiplier. 3. **Get Results**: The numbers update instantly, maintaining the format (e.g., "1 1/2 cups").

Key Features

  • **Smart Text Parsing**: identifies numbers, fractions (1/2), and mixed fractions (1 1/2).
  • **Preserves Text**: Keeps ingredient names and instructions intact.
  • **One-Click Multipliers**: Buttons for Half (0.5x), Double (2x), and Triple (3x).
  • **Custom Scale**: Enter any decimal (e.g., 1.75x) for precise adjustments.

Frequently Asked Questions

Does this change cooking time?

Usually, NO. Cooking temperatures remain the same. However, if you are baking a larger volume (e.g., a thicker cake), the time might increase slightly. Use a toothpick test to check doneness.

Does it convert units?

No, this tool only scales the *numbers*. If you need to convert 'Cups' to 'Grams', use our Ingredient Converter tool.
