CONVERTING TEMPERATURES FROM AN INSTANT-READ THERMOMETER
We include doneness temperatures in many of our recipes, such as those for poultry, meat, and bread. We recommend an instant-read thermometer for the job. Refer to the table above to convert Fahrenheit degrees to Celsius. Or, for temperatures not represented in the chart, use this simple formula:
Subtract 32 degrees from the Fahrenheit reading, then divide the result by 1.8 to find the Celsius reading.
EXAMPLE:
“Roast until the thickest part of the chicken thigh registers 175 degrees on an instant-read thermometer.” To convert:
175˚ F – 32 = 143˚
143˚ ÷ 1.8 = 79.44˚C, rounded down to 79˚C
