Giga joule

What are all these numbers and labels and how do they relate to your day-to-day gas and electric usage in your home? Even more basic, how is energy even measured giga joule calculated? In short, it all comes down to the joule. But just what is a joule, giga joule, anyway?

It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule — In terms of SI base units and in terms of SI derived units with special names , the joule is defined as [ citation needed ]. One joule can also be defined by any of the following: [ citation needed ]. The joule is named after James Prescott Joule. As with every SI unit named for a person, its symbol starts with an upper case letter J , but when written in full, it follows the rules for capitalisation of a common noun ; i. The cgs system had been declared official in , at the first International Electrical Congress.

Do you want to convert joules to gigajoules? Joe is the creator of Inch Calculator and has over 20 years of experience in engineering and construction. He holds several degrees and certifications. Full bio. Since one gigajoule is equal to 1,,, joules, you can use this simple formula to convert:. There are 1,,, joules in a gigajoule, which is why we use this value in the formula above. Gigajoules and joules are both units used to measure energy. Keep reading to learn more about each unit of measure. One gigajoule is equal to 1,,, joules, which is the energy equal to the force on an object of one newton at a distance of one meter. The gigajoule is a multiple of the joule , which is the SI derived unit for energy.

The average Canadian household that uses natural gas consumes about 88 GJ per year. On average, our customers consume about GJ of natural gas annually. Please help improve this article by adding citations to reliable sources. Watts measure power, which is the rate at which electrical devices use energy. In absolute measure its value is 10 7 C. Main article: Newton-metre. Los Alamos National Laboratory. At the fourth congress , the "international ampere" and "international ohm" were defined, with slight changes in the specifications for their measurement, with the "international joule" being the unit derived from them. Showing Alberta. A joule is a measurement of energy. Archived from the original on For example, your vacuum will always require 1 kW of power to function, but you may use 3 kWh of energy in one month—or 10 kWh if your floors are really dirty. For the purposes of calculating your natural gas use in joules, one BTU equals joules. From there, you can estimate your monthly natural gas costs by multiplying your monthly gigajoule consumption e.

.

So, how many gigajoules is that equal to? International Bureau of Weights and Measures. New York. Energy Saving Tips. The cgs system had been declared official in , at the first International Electrical Congress. This may seem like an astronomical figure, but a single joule is actually a very small energy amount. Contact Us. As stated above, natural gas suppliers issue natural gas rates on a per-GJ basis. A report on the changeover from calories to joules in nutrition. In mechanics , the concept of force in some direction has a close analogue in the concept of torque about some angle : [ citation needed ]. At the fourth congress , the "international ampere" and "international ohm" were defined, with slight changes in the specifications for their measurement, with the "international joule" being the unit derived from them.
