how do you convert joules to kilojoules?
example: 2240.48 joules
3887.4 joules
13.85 joules

1456joules= 1.456kJ
k stands for one thousand. 
1 joule = 0.001 kilojoules
2240.48 joules = 2.24048 kilojoules
Just move three decimal places to the left. 
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) = ??
