A Guide to Cooking Conversions

When using a recipe from another country you will find the measures used are interpreted differently.  You may need to experiment to get the exact measure that suits you.

The measurements below are a guide only and are not exact conversions as they have been rounded up or down to keep things simple. 


Volume

Metric Approx. US Equivalent Approx. UK Equivalent
1 teaspoon 5ml 6ml
1 tablespoon 15ml 18ml
1 cup* 235ml 285ml
¼ cup 60ml 70ml
½ cup 120ml 140ml
1 pint 470ml 570ml

*The term "cup" is officially defined as half a pint; however it can be interpreted as a breakfast cup, coffee cup, metric cup, etc. so it is also not always an exact measure.

110º 230º Very slow
120º/130º 250º/260º Very slow
140º 285º Slow
150º 300º Slow
160º/170º 320º/340º Moderate
180º 355º Moderate
190º 375º Moderately hot
200º 390º Moderately hot
220º 430º Hot
230º 445º Hot
240º 465º Very hot

Note: Fan assisted ovens are usually set approximately 25º Celsius (approximately 50º Fahrenheit) lower than others and cooking time can be reduced by 10 minutes for every hour of cooking time.  Of course you need to take your oven into account.

To manually convert degrees Fahrenheit to degrees Celsius, subtract 32 from the Fahrenheit temperature, multiply the difference by 5, and then divide by 9,  i.e. 68°F – 32 = 36 ÷ 1.8 = 20°C
To convert degrees Celsius to degrees Fahrenheit, simply multiply the Celsius temperature by 1.8 and add 32, i.e. 20°C x 1.8 = 36 + 32 = 68°F.

Some common temperature facts:

  • Freezing = 0°C , 32°F
  • Room temperature = 20°C , 68°F
  • Normal body temperature = 37°C , 98.6°F
  • A very hot day = 40°C , 104°F
  • Boiling point of water = 100°C , 212°F
