WebWith dimensional analysis, you multiply by the conversion factors in such a way as to take what you started with and get the units to cancel until you get what you wanted. Thus, to convert kJ to J you do the following: 1 kJ × (1000 J / 1 kJ) = 1000 J Notice that the kJ cancel out and you're left with J as you units.
