What Is a Recipe Converter?
A recipe converter scales ingredient quantities when you need to cook for more or fewer people than a recipe was written for. Instead of doing fraction math in your head, this tool recalculates every ingredient proportionally in one click.
Whether you're doubling a cookie recipe for a party, halving a casserole for two, or converting a restaurant-sized batch down to a home kitchen quantity, the recipe converter handles all the arithmetic instantly and accurately.
How to Use the Recipe Converter
1. Enter each ingredient with its amount and unit.
2. Set the original number of servings.
3. Enter your desired number of servings or pick a multiplier.
4. Copy or print the scaled ingredient list.
Key Features
Instant proportional scaling works with any number of servings, not just simple doubles or halves. Fractional amounts are displayed as clean, practical measurements. The tool runs entirely in your browser with no data sent to any server, keeping your family recipes private.
Frequently Asked Questions
How do I scale a recipe for more servings?
Enter your recipe ingredients and the original serving count, then type in the new number of servings you want. The tool instantly recalculates every ingredient amount proportionally — no manual math needed.
Can I halve or quarter a recipe?
Yes. Set your target servings to any number smaller than the original and all ingredients will be scaled down proportionally. The tool handles fractions cleanly so you get practical measurements.
Does it convert between metric and imperial units?
The tool focuses on proportional scaling — if your recipe uses cups, the scaled version uses cups. For unit conversion between metric and imperial, check our Cooking Converter tool.
How accurate is the recipe scaling?
The math is exact — every ingredient is multiplied by the same ratio. For baking recipes, keep in mind that some ingredients like yeast and leavening agents may not scale perfectly linearly at very large multipliers.
Can I save my scaled recipes?
You can copy the scaled ingredient list to your clipboard or print the page. The tool runs entirely in your browser, so your recipes stay private and are never stored on any server.
