Conversion formulas

Conversion formulas
ConversionFormula
Fahrenheit to Celsius°C = (°F − 32) × 5/9212°F = (212 − 32) × 5/9 = 100°C
Celsius to Fahrenheit°F = (°C × 9/5) + 32180°C = (180 × 9/5) + 32 = 356°F
Gas mark to Celsius°C = (gas mark × 14) + 121Gas mark 6 = (6 × 14) + 121 = 205°C
Gas mark to Fahrenheit°F = (gas mark × 25) + 250Gas mark 6 = (6 × 25) + 250 = 400°F

Thermometer tips

4 lists
Oven5 tips
  1. Preheat oven for 15–20 minutes before baking.
  2. Use an oven thermometer to verify temperature.
  3. Reduce temperature by 25°F for convection ovens.
  4. Allow oven to recover temperature between batches.
  5. Check for hot spots by baking a sheet of bread.
Meat5 tips
  1. Insert thermometer into thickest part of meat.
  2. Let meat rest 5–10 minutes after cooking.
  3. Temperature will rise 5–10°F during resting.
  4. Clean thermometer between different meats.
  5. Check multiple spots for large cuts.
Candy5 tips
  1. Use a candy thermometer for accuracy.
  2. Don't stir once sugar starts boiling.
  3. Test in cold water for doneness.
  4. Work quickly once desired temperature is reached.
  5. Make candy on a dry day: humidity keeps sugar from setting hard.
General4 tips
  1. Calibrate in ice water: it should read 32°F (0°C); adjust or allow for the difference.
  2. A digital instant-read settles in a few seconds; a dial thermometer needs 15–20.
  3. Keep the probe clean and dry between readings.
  4. Water boils about 1°F lower for every 500 feet of altitude, so candy and boiling times shift with it.
