Monitoring these figures can lead to more informed decisions about energy use and conservation strategies.

Electric Vehicles (EVs):
 In the context of electric vehicles, watt hours are critical in determining the range and efficiency of a vehicle. The battery capacity in electric vehicles is often expressed in kilowatt hours (kWh), where 1 kWh equals 1000 Wh. Understanding how many watt hours an EV uses per mile can help potential buyers assess its efficiency and suitability for their needs.
Converting Watt Hours
It might be necessary to convert watt hours into other energy units depending on the application. Here are some common conversions:

Kilowatt Hours (kWh):
Since 1 kWh = 1000 Wh, to convert watt hours to kilowatt hours, simply divide by 1000:[ \text{kWh} = \frac{\text{Wh}}{1000} ]

Joules:
Using the conversion factor (1 Wh = 3600 J since there are 3600 seconds in one hour):[ \text{J} = \text{Wh} \times 3600 ]
