how do you convert joules to kilojoules?

example: 2240.48 joules
3887.4 joules
13.85 joules

  • chemistry -

    1456joules= 1.456kJ

    k stands for one thousand.

  • chemistry -

    1 joule = 0.001 kilojoules

    2240.48 joules = 2.24048 kilojoules

    Just move three decimal places to the left.

  • chemistry -

    It's just like converting any unit from the unit to the kilounit.
    1000 J = 1 kJ.
    2240.48 J x (1 kJ/1000 J) = ??
