What does one watt-hour represent?

One watt-hour is the energy produced or consumed by one watt of power operating for one hour, equal to 3,600 joules.

Why convert watt-hours to kilowatt-hours?

Converting to kilowatt-hours makes energy values easier to manage and is standard for billing, battery ratings, and energy reporting.

Can I convert fractional values accurately?

Yes, but small watt-hour amounts result in fractional kilowatt-hours that need careful handling depending on your application.
