You can do the reverse unit conversion from attojoule to yottajoule, or enter any two units below:

yottajoule to kilocalorie

yottajoule to thermie

yottajoule to quad

yottajoule to gigajoule

yottajoule to electron volt

yottajoule to hectowatt-hour

yottajoule to hectojoule

yottajoule to horsepower hour

yottajoule to kilopond meter

yottajoule to zettajoule

The SI prefix "yotta" represents a factor of
10^{24}, or in exponential notation, 1E24.

So 1 yottajoule = 10^{24} 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 "atto" represents a factor of
10^{-18}, or in exponential notation, 1E-18.

So 1 attojoule = 10^{-18} 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).
