How to Convert eV to Joules
The electron volt (eV) is a common unit of energy in atomic and particle physics. To convert it to the standard SI unit of energy (joule), you use a fixed conversion factor.
Formula
Step-by-step Process:
- Take the value in electron volts (eV).
- Multiply it by 1.602176634 × 10^-19.
- The result is the energy in joules (J).
Example Calculation
Convert 5 eV to joules:
Step 1: Write the formula
Energy (J) = eV × 1.602176634 × 10^-19
Step 2: Insert the value
Energy = 5 × 1.602176634 × 10^-19
Step 3: Calculate
Energy = 8.01088317 × 10^-19 J
Final Answer:
5 eV = 8.01 × 10^-19 joules
