Search Australia updated to easily provide calorie content of food.

A common search we're carrying out at the moment is the energy content of different food. Yes, we're dieting, so it does help if you can work out quickly the energy content of different food. For example, how many kilojoules are there in an apple?

Interestingly Google provides this information. The information returned is in Calories, but multiplying by four (actual conversion is to multiple by 4.2) is fairly easy and gives an approximation of the energy in kilojoules. (Note the use of the upper case in Calories. I've explained this below.)

I decided to make it even easier for myself and those using Search Australia. If you now enter the letter 'c' followed by a space and then the food item, you'll get the Calories for the food. There is a selection option which enables you to vary the size of the food item.

So now if you want to know the energy content of an apple, just enter 'c apple' in Search Australia and there's your answer.

PS. When referring to energy content in kilojoules is easy. However, the terms calorie and Calorie are frequently interchanged and can cause some confusion. Calorie with a capital is 1000 calories. If the number you're expecting to see is out by a factor of a thousand then this is the reason. The energy content of food is often shown in Calories and kilojoules. If you see the energy content shown as calories, chances are it is an error and the word calories should have been capitalised. When we write about the energy content of food is it OK to use the word calorie, but do keep in mind when we are using the measurement of the amount of energy in a food item, we are usually referring to the Calorie value in capital 'c', because it is a more convenient smaller number. That is 1 Calorie equals 1000 calories. 1 Calories equals 4.2 kilojoules. 1 calorie equals 4.2 joules. 1 Calorie is also known as a kilocalorie.
