Converting Joules (J) to Kilojoules (kJ) is simple. Why is it simple? Because it only requires one basic operation: multiplication. The same is true for many types of unit conversion (there are some expections, such as temperature). To convert Joules (J) to Kilojoules (kJ), you just need to know that 1joules is equal to kJ. With that knowledge, you can solve any other similar conversion problem by multiplying the number of Joules (J) by . For example, 5joules multiplied by is equal to kJ.

We define the "best" unit to convert a number as the unit that is the lowest without going lower than 1. For 5 joules, the best unit to convert to is .

1 joules = kJ

5 joules = kJ

10 joules = kJ

15 joules = kJ

25 joules = kJ

100 joules = kJ

1000 joules = kJ

1 kJ = joules

5 kJ = joules

10 kJ = joules

15 kJ = joules

25 kJ = joules

100 kJ = joules

1000 kJ = joules
