Approximate Temperatures

To change from degrees Fahrenheit to degrees Celsius, subtract 32, then multiply by 5/9. For example: 68°F - 32 = 36;36 x 5/9 = 20°C.

To convert degrees Celsius to degrees Fahrenheit, multiply the degrees by 9/5, then add 32 to that figure.For example: 20°C x 9/5 = 36; 36 + 32 = 68°F.

Metric Equivalents


One of the secrets of good cooking is to keep ingredients in their proportions. So whenever you use a recipe from this book, measure precisely if you want consistent success. Be aware, however, that U.S. liquid measures, used in these recipes, are not identical to their Canadian namesakes. For example, an American quart is about 8 (Canadian) ounces (1 cup) less than a Canadian quart.
