What are kiojoules?

Answer 1

A Joule is a unit of work and energy, equal to the work done when a force of one newton moves through a distance of one metre in the direction of the force.

It was named after James Joule (1818-89) who was a British natural philosopher.

A Kilojoule equals 1000 joules or 238.8459 Calories

Answer 2

Kilojoules are used in some countries to measure the energy contained in food; food energy is more often measured in calories; the energy depends on the type of food. So look up a calorie to kilojoule converter: http://richardjackson.org/calorie.html

Now, just for fun, let's enter a weeks worth of calories for a 2,000 calorie per day diet, 7 x 2,000 = 14,000 calories, convert it to kilojoules, and see what the answer is:

58,800 kilojoules

So we now know that kilojoules measure energy in smaller increments than do calories. The above is true if you live in the United States but most countries measure food energy in kilojoules.

Answer 3

Kiojoules is a unit of energy, referring to the energy value of food and how much energy our bodies burn. Another word for kiojoules is calories.
