Understanding Energy Conversion

What is a Gigajoule?

A gigajoule (GJ) is a unit of energy equal to one billion (109) joules. It's commonly used in large-scale energy measurements, such as industrial processes and power generation. One gigajoule is approximately equivalent to:

  • 277.8 kilowatt-hours
  • The energy content of 26 liters of gasoline
  • The electricity used by a typical household over 10 days

What is a Watt-Second?

A watt-second (Ws) is equivalent to one joule and represents the energy expended when one watt of power is sustained for one second. This unit is particularly useful in:

  • Electronic systems design
  • Power consumption calculations
  • Energy storage specifications
