What is Milliwatt-hour to Gigawatt-hour Conversion?
Milliwatt-hour (mWh) and gigawatt-hour (GWh) 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 milliwatt-hour to gigawatt-hour, knowing the exact conversion formula is essential.
MWh to gwh Conversion Formula:
One Milliwatt-hour is equal to 1e-11 Gigawatt-hour.
Formula: 1 mWh = 1e-11 GWh
By using this conversion factor, you can easily convert any energy from milliwatt-hour to gigawatt-hour with precision.
How to Convert mWh to GWh?
Converting from mWh to GWh is a straightforward process. Follow these steps to ensure accurate conversions from milliwatt-hour to gigawatt-hour:
- Select the Milliwatt-hour Value: Start by determining the milliwatt-hour (mWh) value you want to convert into gigawatt-hour (GWh). This is your starting point.
- Multiply by the Conversion Factor: To convert milliwatt-hour to gigawatt-hour, multiply the selected mWh value by 1e-11. This factor is essential for accurately converting from a larger unit (mWh) to a much smaller unit (GWh).
- Illustration of Multiplication:
- 1 mWh = 1e-11 GWh
- 10 mWh = GWh
- 100 mWh = GWh
- Find the Conversion Result: The result of this multiplication is your converted value in gigawatt-hour unit. This represents the same energy but in a different unit.
- Save Your Gigawatt-hour Value: After converting, remember to save the result. This value represents the energy you initially measured, now expressed in gigawatt-hours.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the milliwatt-hour value by 1e+12. This alternative method also gives you the correct energy in gigawatt-hours.
- Illustration of Division:
- GWh = mwh ÷ 1e+12
