we use kilojoules (kJ) to measure how much energy people get from consuming a food or drink. The kilojoule content of foods depends on the amount of carbohydrates, fats and proteins present in the food, and the portion size. a joule is so small that energy is often measured in batches of 1000 joules. A batch of 1000 joules is known as a kilojoule (kJ). ... Food energy is commonly measured in kilojoules (kJ). Even larger amounts of energy, such as electrical energy, are measured in megajoules (MJ).

What is the unit measured in energy?
The international (that is, the SI) unit for energy is the Joule.
Food energy is commonly expressed in kcalories and in?
... and in the SI unit for energy, i.e., the Joule. Kilojoules
Why is food measured in kilojoules?
It is a more convenient unit of measurement.
What energy is measure in?
A: Energy is measured in joules and kilojoules. One joule is the amount of energy needed to lift 100 grams to 1 kiliogram.
What are kilojoules and calories?
1 calorie is the old fashioned unit of energy. 1 Joule is the SI unit of energy and is the same as a newton.meter
What are International units of energy are expressed in?
They are not expressed in joules, they are expressed in volts.
What is the English measurement of thermal energy?
Traditionally the BTU (British Thermal Unit), but now we usually use kilojoules
Who are bigger a joule or a megaton?
How many kilojoules in 1 megajoules? The answer is 1000. We assume you are converting between kilojoule and megajoule. You can view more details on each measurement unit: kilojoules or megajoules. The SI derived unit for energy is the joule. 1 joule is equal to 0.001 kilojoules, or 1.0E-6 megajoules
In chemistry what does KJ mean?
That is an abbreviation for a kilojoules, a metric measure of energy.
Convert kilojoules to watts?
The energy in kilojoule cannot be converted to the power in watts. The time is missing. But you can convert kilojoules to kilowatthours (kWh). Scroll down to related links and look at "Energy Converter".
Why do you use kilojoules to measure?
Some times the amount of energy will be in larger amount. If we use joule then larger number with many zeros has to be used. So we use kilo joule then smaller number would fulfill our need.
