How do I resize a recipe? ›

The way to scale a recipe by number of servings is to multiply the original amount by the desired serving size and then divide by the original serving size. We are essentially doing the same thing as scaling a recipe by a multiplier.

You simply multiply or divide the ingredients to get the new yield; for example, doubling everything to get twice as many servings or halving everything to get half as many. But not every recipe is so straightforward, and there are some considerations to keep in mind.

The most common way to adjust recipes is to use the conversion factor method. This requires only two steps: finding a conversion factor and multiplying the ingredients in the original recipe by that factor.

To convert between ratio scales, you need to multiply or divide both sides of the ratio by the same number. For example, to convert 1:100 to 1:50, you need to multiply both sides by 2. To convert 1:50 to 1:100, you need to divide both sides by 2.

Officially, a US Cup is 240ml (or 8.45 imperial fluid ounces.) This is slightly different from an Australian, Canadian and South African Cup which is 250ml. As long as you use the same cup for measuring out each of your ingredients, the proportions should work out the same.

Calculate the scaling factor by dividing the number of servings (or grams) you want to make by the recipe yield. Example: This recipe yields five servings. If you are making nine servings, the scaling factor is 9 ÷ 5 = 1.8.

The trick is to switch your measurements to units that are simpler to split, such as tablespoons and teaspoons. Key Measurement Conversions for Scaling Down Recipes: 1 cup = 16 tablespoons (tbsp) = 48 teaspoons (tsp) Half of 1 cup = 8 tablespoons = 24 teaspoons.

A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.

The scale factor is commonly expressed as 1:n or 1/n, where n is the factor. For example, if the scale factor is 1:8 and the real measurement is 32, divide 32 ÷ 8 = 4 to convert. To convert a smaller, scaled measurement up to the actual measurement, simply multiply the scaled measurement by the scale factor.

If you need eight servings and the recipe makes six: 8 ÷ 6 = 1.3. This is your conversion factor which you'll use to find out how much of each ingredient you'll need. Second, multiply each ingredient in your recipe by the conversion factor. Third, round up or down a little bit when conversions are hard to measure.
