Quick Answer: Is Q A Joule Or KiloJoule?

What does kJ mean in texting?

KilljoyKJ means “Killjoy”..

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.

Is Joules the same as kilojoules?

Joules to Kilojoules Conversion 1 Joule (J) is equal to 0.001 kilojoule (kJ). … For example, to convert 100 J to kJ, divide 100 by 1000, that makes 0.1 kJ is 100 J.

What is the formula of Joule?

In words: Work is equal to the force that is exerted times the distance over which it is exerted. In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph.

Is 1 Joule a lot?

This is due to the fact that a joule is an extremely small amount of energy. To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it. A kilowatt-hour is equal to 3,600,000 joules.

What can 1 Joule of energy do?

This is the stable version, checked on 8 July 2011. The joule (symbol J) is the SI unit of energy—a measure of the capacity to do work or generate heat. One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m).

How many kJ is 1j?

How do you write kilojoules?

PronunciationIPA: /ˈkiloˌjou̯le/, [ˈkilo̞ˌjo̞u̯le̞]Rhymes: -oule.Syllabification: ki‧lo‧jou‧le.

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.”

How do you convert kJ to Watts?

1 Kilojoule is equal to 0.277777778 watt hour (Wh). To convert kilojoules to Wh, multiply the kilojoule value by 0.277777778 or divide by 3.6. What is Watt hours? Watt hours is a metric system energy unit.

What SI unit is Joule?

Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.

How many kilojoules do you need to burn to lose 1 kg?

37,000kJ1 kilogram of body fat contains the equivalent of 37,000kJ. So to lose weight, you need to create a deficit of 37,000kJ.

What is TJ in energy?

A terajoule is a unit of energy in the International System of Units (SI). The symbol for terajoule is TJ. The base unit for a terajoule is joule and the prefix is tera.

Is heat measured in joules or kilojoules?

Heat (Energy) The SI-unit of heat – or energy – is joule (J). Other units used to quantify heat are the British Thermal Unit – Btu (the amount of heat to raise 1 lb of water by 1oF) and the Calorie (the amount of heat to raise 1 gram of water by 1oC (or 1 K)).

How much energy is a Kilojoule?

Energy as kilojoules A kilojoule is a unit of measure of energy, in the same way that kilometres measure distance. Food energy used to be measured in Calories (Cal) and some countries still use those units. The conversions are as follows: 1 kJ = 0.2 Cal.

Which quantity is equal to 50 kJ?
