Kilojoules to Joules Converter
How to convert kilojoules to joules
joules = kilojoules × 1,000
To convert kilojoules to joules, multiply the number of kilojoules by 1,000.
1 kJ = 1,000 J
Examples
- The EU daily reference intake for an adult: 8,400 kJ × 1,000 = 8,400,000 J
- 500 kJ × 1,000 = 500,000 J
Good to know
One kilojoule is exactly 1000 joules.
