Recipe Converter
Scale any recipe up or down with ease. Enter your ingredients, adjust serving sizes, and convert between measurement units (cups, grams, milliliters, ounces, and more). Perfect for cooking, baking, and meal prep planning.
How the Recipe Converter Works
This recipe converter scales your recipes up or down by calculating a conversion factor based on the original and desired serving sizes. Each ingredient quantity is multiplied by this factor.
Conversion Factor = Desired Servings ÷ Original Servings
For example: A recipe makes 24 cookies but you want 12 cookies.
Conversion Factor = 12 ÷ 24 = 0.5
Each ingredient quantity is multiplied by 0.5.
The calculator also supports:
- Unit Conversion: Automatically convert between US customary (cups, tablespoons) and metric (grams, milliliters) units.
- Fraction Display: Show ingredient quantities as fractions for easy measuring (e.g., 1½ cups instead of 1.5 cups).
- Flexible Ingredients: Add, remove, and modify ingredients as needed.
Tips for Scaling Recipes
- Baking Accuracy: For baking, use a kitchen scale for precise measurements. Volume measurements (cups) can vary significantly.
- Cook Times: Scaling a recipe may affect cooking times. Larger portions may need more time; smaller portions may cook faster.
- Spices & Seasonings: When scaling, you may want to adjust spices to taste rather than using the exact factor.
- Pan Sizes: When doubling or halving a recipe, consider whether your pan size needs to change.
- Eggs: Scaling recipes that use whole eggs can be tricky — use the "each" unit for eggs.
❓ Recipe Converter FAQ
How do I scale a recipe?
Enter the original number of servings and the desired number of servings. The calculator will compute a conversion factor and adjust all ingredient quantities accordingly.
What is a conversion factor?
The conversion factor is the ratio of desired servings to original servings. Multiply each ingredient quantity by this factor to scale the recipe. For example, a factor of 0.5 halves the recipe, while 2 doubles it.
Can I convert between US and metric units?
Yes. In the advanced options, select "Yes (US to Metric)" to convert cups, tablespoons, and teaspoons to grams and milliliters, or "Yes (Metric to US)" to convert the other way.
How do I add more ingredients?
Click the "➕ Add Ingredient" button at the bottom of the ingredient list. You can add as many ingredients as you need.
How do I remove an ingredient?
Click the "✕" button next to any ingredient to remove it from the list.
What units are supported?
The calculator supports cups, tablespoons (tbsp), teaspoons (tsp), ounces (oz), grams (g), kilograms (kg), milliliters (ml), liters (l), pinch, each, and whole.
Can I see ingredient quantities as fractions?
Yes. Enable "Show as Fractions" in the advanced options to display quantities as fractions (e.g., 1½ cups instead of 1.5 cups).
What is the difference between volume and weight measurements?
Volume measurements (cups, tablespoons) measure the space an ingredient occupies. Weight measurements (grams, ounces) measure the actual mass. Weight is more accurate for baking because different ingredients have different densities.
How do I convert cups to grams?
Different ingredients have different densities, so there's no single conversion factor. This calculator provides approximate conversions based on standard ingredient densities (e.g., flour ~120g/cup, sugar ~200g/cup).
Can I convert between tablespoons and milliliters?
Yes. 1 tablespoon ≈ 15 ml. The calculator will automatically convert between volume units when the conversion option is enabled.
What should I do when scaling eggs?
Use the "each" unit for eggs. When scaling, the calculator will multiply the number of eggs by the conversion factor. For example, 2 eggs × 0.5 = 1 egg.
How do I scale a recipe that uses whole numbers of eggs?
When the conversion factor results in a fraction of an egg (e.g., 1.5 eggs), you may need to round or use a different approach. For best results, use a scale and weigh the eggs.
Does scaling a recipe affect cooking time?
Yes. Larger portions may need more cooking time, while smaller portions may cook faster. Always check for doneness rather than relying solely on time.
Can I use this calculator for baking?
Absolutely! This calculator is especially useful for baking, where precise measurements are important. Just be sure to use weight measurements (grams) for best accuracy.
How do I copy the converted recipe?
Click the "📋 Copy Recipe" button below the results table. The recipe will be copied to your clipboard in a readable format.
What is the difference between a pinch and a dash?
A pinch is approximately 1/16 teaspoon, while a dash is roughly 1/8 teaspoon. This calculator treats them as separate units but both are very small amounts.
How do I convert a recipe from a different country?
Use the unit conversion feature to convert between US and metric units. Enter the ingredients as listed, then select the conversion direction in advanced options.
Is this calculator accurate for all ingredients?
The calculator provides accurate scaling based on the conversion factor. Unit conversions are approximate based on standard ingredient densities. For best results in baking, use a kitchen scale.
Can I save my converted recipe?
You can copy the recipe to your clipboard or download it (coming soon). For now, we recommend copying the recipe and pasting it into your preferred document or recipe app.
