What is Electron-volt to Millijoule Conversion?
Electron-volt (eV) and millijoule (mJ) are both units used to measure energy, but they serve different purposes depending on the scale of the measurement. If you ever need to convert electron-volt to millijoule, knowing the exact conversion formula is essential.
EV to mj Conversion Formula:
One Electron-volt is equal to 1.441959e-14 Millijoule.
Formula: 1 eV = 1.441959e-14 mJ
By using this conversion factor, you can easily convert any energy from electron-volt to millijoule with precision.
How to Convert eV to mJ?
Converting from eV to mJ is a straightforward process. Follow these steps to ensure accurate conversions from electron-volt to millijoule:
- Select the Electron-volt Value: Start by determining the electron-volt (eV) value you want to convert into millijoule (mJ). This is your starting point.
- Multiply by the Conversion Factor: To convert electron-volt to millijoule, multiply the selected eV value by 1.441959e-14. This factor is essential for accurately converting from a larger unit (eV) to a much smaller unit (mJ).
- Illustration of Multiplication:
- 1 eV = 1.441959e-14 mJ
- 10 eV = mJ
- 100 eV = mJ
- Find the Conversion Result: The result of this multiplication is your converted value in millijoule unit. This represents the same energy but in a different unit.
- Save Your Millijoule Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in millijoules.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the electron-volt value by 6.241509e+15. This alternative method also gives you the correct energy in millijoules.
- Illustration of Division:
- mJ = ev ÷ 6.241509e+15
