Information About

Gigajoule

A gigajoule (GJ) is 1,000,000,000 Joule s. It is a unit of Energy .

EXAMPLES

One gigajoule is the amount of energy a computer/screen combination using 500 Watt consumes in approx. 23 days.

One gigajoule equals the amount of energy consumed by a 100 Watt light bulb in approx. 4 months.

A car with a mass of 700 kg travelling at 70 km/h stores approx. 0.00013 GJ of kinetic energy.

The ATLAS_experiment contains a magnet storing 1.2 GJ in its magnetic field.

--- Hence, the magnetic field of the ATLAS experiment at CERN stores about the same amount of energy as 10000 such cars all moving at 70 km/h.

COMPARISON

To help compare different Orders Of Magnitude we list here Energies between a gigajoule (1 GJ, 10⁹ Joule s) and 10¹⁰ joules.

Weaker Energies

1.5 × 10⁹ J – energy in an average Lightning bolt

1.6 × 10⁹ J – energy in an average tankful ( 45 Litres ) of Petrol

1.956 × 10⁹ J – Planck Energy

3.2 × 10⁹ J – 900 kWh: approximate annual power use of a standard clothes dryer

3.6 × 10⁹ J – 1,000 KWh

4.184 × 10⁹ J – energy released by explosion of 1 Tonne of TNT
