Full precision:1000 J
Step-by-Step Solution
To convert 1 kj to joules, we multiply by 1000 because one kilojoule equals exactly 1000 joules.
1 kilojoule = 1000 joules
Since each kilojoule contains 1000 joules, we multiply our value by this factor:
1 × 1000 = 1000 joules
So 1 kj = 1000 joules.
Quick check: 1000 ÷ 1000 = 1 kj
Example Conversions
Example 1: 1 kJ = 1000 J
1 × 1000 = 1000
1 × 1000 = 1000
Example 2: 5 kJ = 5000 J
5 × 1000 = 5000
5 × 1000 = 5000
Example 3: 10 kJ = 10000 J
10 × 1000 = 10000
10 × 1000 = 10000
