Converting Kilojoules (kJ) to Joules (J) 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 Kilojoules (kJ) to Joules (J), you just need to know that 1kJ is equal to joules. With that knowledge, you can solve any other similar conversion problem by multiplying the number of Kilojoules (kJ) by . For example, 7kJ multiplied by is equal to joules.

We define the "best" unit to convert a number as the unit that is the lowest without going lower than 1. For 25 kilojoules, the best unit to convert to is .

1 kJ = joules

5 kJ = joules

10 kJ = joules

15 kJ = joules

25 kJ = joules

100 kJ = joules

1000 kJ = joules

1 joules = kJ

5 joules = kJ

10 joules = kJ

15 joules = kJ

25 joules = kJ

100 joules = kJ

1000 joules = kJ
