What is the difference between kilojoules and joules?
Kilojoules to Joules Conversion 1 Kilojoule (kJ) is equal to 1000 joules (J).
To convert kilojoules to joules, multiply the kilojoule value by 1000.
For example, to convert 20 kJ to J, multiply 20 by 1000, that makes 20 kJ is 20000 J.
What is a Kilojoule?.
How many kilojoules are in a banana?
Snack wise Banana bread might sound healthy but it can contain as much as 2,500kJ. Take a real banana, at about 400kJ, in your lunch box instead. This is a very easy way to save 2,000kJ.
How many kilojoules are in a Juul?
What is 1 kilojoule in joules? 1 kJ to J conversion. A kilojoule is 1,000 joules.
What is kcal in food?
Checking calories in food The calorie content is often given in kcals, which is short for kilocalories, and also in kJ, which is short for kilojoules. A kilocalorie is another word for what’s commonly called a calorie, so 1,000 calories will be written as 1,000kcals. Kilojoules are the metric measurement of calories.
What are kilojoules to calories?
Energy in food and drinks is measured by the number of kJ (kilojoules) it provides. kJ are similar to Calories: 1 kJ = 0.2 Calories (Cals) 1 Calorie = 4.2 kJs.
What is a kJ equal to?
one thousandThe kilojoule (kJ) is equal to one thousand (103) joules. Nutritional food labels in most countries express energy in kilojoules (kJ). One square metre of the Earth receives about 1.4 kilojoules of solar radiation every second in full daylight.
Why do we use kilojoules instead of joules?
Countries in the European Union use kilojoules on their labels, the joules are the standard measurement of energy. However, the use of calories over joules on American food labels is simply a preference — think of it as the energy equivalent of using “miles” instead of “kilometers.”
Is Joules bigger than kilojoules?
Exa (E=1018). Thus, a kiloJoule (kJ) is 1000 Joules and a megaJoule (MJ) is 1,000,000 Joules. A related unit is the Watt, which is a unit of power (energy per unit time).
How many kilojoules should you eat a day?
It’s all about the balance between energy (or kilojoules) in and energy (or kilojoules) out. Sometimes 8,700 kJ per day is used as an approximate figure for the ‘average’ Australian to maintain their weight.
How many joules are in a Joule?
0.0010 JThe joules unit number 0.0010 J converts to 1 mJ, one millijoule.

What foods are high in kilojoules?
Foods that are high in fats, added sugars or alcohol are by far the highest in kilojoules. Foods such as fruits, vegetables and legumes are lower in kilojoules. You can find out how many kilojoules are in packaged foods by checking the label.
What is Joule formula?
In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph. In symbols: W = F x d. In practical terms, even a small force can do a lot of work if it is exerted over a long distance.
Is 5000 kJ a day enough?
LEDs prescribe a daily energy intake of about 4,200 to 5,000 kJ per day. This is usually a list of specific meals and snacks that you follow closely to ensure your kilojoule intake matches the daily target.
How many kilojoules are in 2 eggs?
How many calories in two eggs? An average serving size of two eggs contains only 148 calories or 620 kilojoules – roughly the same as two apples.
