How to Convert Microjoules to Joules
A millijoule is a smaller unit of energy, where “milli-” indicates one-thousandth (10-3) of a joule, the standard SI unit of energy. 1 joule (J) = 1,000 millijoules (mJ), so multiply joules by 1,000 to convert to millijoules.
Conversion Formula
Quick Trick: 1 Microjoule = 0.001 Joules!
Let’s Solve One Together
Imagine you have an energy measurement:
- We measured: 5,000 microjoules
Here’s how we figure it out:
1. Take our formula: J = µJ × 0.001
2. Put in 5,000 microjoules
3. J = 5,000 × 0.001
Answer: 5 J
Definitions of Key Terms
Microjoule (µJ)
A microjoule (µJ) is a unit of energy that is one-millionth of a joule. It is commonly used to measure small amounts of energy in various applications, particularly in electronics and physics.
Joule (J)
The joule is the standard unit of energy in the International System of Units (SI). It represents the energy transferred when a force of one newton moves an object one meter. Joules are widely used in physics and engineering to measure energy, work, and heat.
