How to convert from kJ to J?
Understand the Problem
The question is asking how to convert kilojoules (kJ) to joules (J), which involves using a conversion factor since 1 kilojoule equals 1000 joules.
Answer
Multiply by 1000
Answer for screen readers
To convert kilojoules to joules, multiply by 1000.
Steps to Solve
- Understand the conversion factor
1 kilojoule (kJ) is equal to 1000 joules (J). This means that to convert from kilojoules to joules, we need to multiply by 1000.
- Set up the conversion equation
If you have a value in kilojoules (let's call it $k$), then the value in joules (let's call it $j$) can be found by multiplying $k$ by 1000:
$$ j = k imes 1000 $$
- Apply the conversion to an example
Let's say we have 5 kJ. To convert to joules, we multiply by 1000:
$$ 5 ext{ kJ} imes 1000 = 5000 ext{ J} $$
To convert kilojoules to joules, multiply by 1000.
More Information
This conversion is based on the metric system where 'kilo-' signifies a factor of 1000.
Tips
A common mistake is to divide by 1000 instead of multiplying. Remember that 'kilo-' means 1000, so you need to multiply.
