Convert 1 joules (J) to kilojoules (kJ) with formulas, examples, and conversion tables.
J
kJ
1 J = 0.001 kJ
Full precision:0.001 kJ
Step-by-Step Solution
To convert 1 joules to kilojoules, we divide by 1000 because one kilojoule equals exactly 1000 joules.
1 kilojoule = 1000 joules
Since there are 1000 joules in every kilojoule, we divide our value by this factor:
1 ÷ 1000 = 0.001 kilojoules
So 1 joules = 0.001 kilojoules.
Quick check: 0.001 × 1000 = 1 joules
