Joules, as is the international Standard. 1 W•h = 3.6 kJ. One of the issues with watt-hours is that they’re so unconventional a unit that people think they’re a rate of change (Watts over time - W/h) which would be a measure of the fluctuation in wattage or colloquially an acceleration of energy. You so often see people doing crazy broken math with them as a result.
How do people dare to measure the amount of work?
