Converting Fahrenheit to Celsius in the Kitchen

Recall:

Convert degrees from Fahrenheit (F) to Celsius (C):

• Subtract 32 from the Fahrenheit temperature, multiply by 5, then divide by 9.

If the temperature is 350 °F, you would subtract 32 to get 318, then multiply by 5 for 1,590 which divided by 9 equals 176.66.  That is then rounded up to 180 °C.

Using a Scale (by Wendy Okopski)

We often encounter recipes at home that are measured by cups. In industry, the recipes are usually in grams/kilograms or ml/L. Generally, the volume of 1 cup is equal to 250ml and is easily converted. Let’s say you need to multiply a home style recipe from 1 recipe to 4x the recipe to adapt to an industry setting.

• If the recipe calls for 1 cup, multiply 4 × 250ml = 1 L of liquid.
• If the recipe calls for 2 cups multiply 2 × 250ml = 500 ml of liquid.

For weighed ingredients, it is important to remember that different items will weigh more than others. Experiment to see how each item differs in weight.

Remember to weigh the empty cup first, and tare the scale to get an accurate weight. Level each ingredient carefully.

If you need to convert a home style recipe from 1 cup of flour to a recipe that needs 1.2 kg of flour, you will need to know how much 1 cup of flour weighs in order to make that calculation.

• 1 cup of flour = 150g
• 1.2kg of flour = 1200g
• 1200 ÷ 150 = 8

You would need to multiply the flour in your recipe × 8
