You can do the reverse unit conversion from kJ to petajoule, or enter any two units below:
The SI prefix "peta" represents a factor of 1015, or in exponential notation, 1E15.
So 1 petajoule = 1015 joules.
The definition of a joule is as follows:
The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889).
The SI prefix "kilo" represents a factor of 103, or in exponential notation, 1E3.
So 1 kilojoule = 103 joules.
The definition of a joule is as follows:
The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889).
