Convert gigajoule to attojoule

Please provide values below to convert gigajoule [GJ] to attojoule [aJ], or Convert attojoule to gigajoule.

1 GJ = 1.0000e+27 aJ. To convert gigajoule to attojoule, multiply the value by 1.0000e+27; to go the other way, divide by it (1 aJ = 1.0000e-27 GJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

  • 1 GJ = 1.0000e+27 aJ
  • 1 aJ = 1.0000e-27 GJ
  • 10 GJ = 1.0000e+28 aJ
  • 100 GJ = 1.0000e+29 aJ



How to Convert Gigajoule to Attojoule

1 GJ = 1e+27 aJ

Example: convert 15 GJ to aJ:
15 GJ = 15 × 1e+27 aJ = 1.5e+28 aJ

Gigajoule

A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.

History/Origin

The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.

Current Use

Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.


Attojoule

An attojoule (aJ) is a unit of energy equal to 10^-18 joules.

History/Origin

The attojoule was introduced as part of the SI prefixes to measure extremely small amounts of energy, particularly in fields like nanotechnology and quantum physics, as the need to quantify very tiny energy scales grew.

Current Use

The attojoule is used in scientific research to measure minute energy quantities, such as in nanotechnology, quantum computing, and molecular biology, where energies involved are extremely small.
