- a_cardboard_box 3y agoWatts per hour are not a unit of power or energy. Watts are power. Watt hours are energy.

- olddustytrail 3y agoThey are both energy. Watts are Joules/seconds so if you're dividing by time and then multiplying by time (an hour in this case) they obviously cancel out and you end up back with just Joules. Specifically 1 Watt-hour==3600 Joules.
- nyrikki 3y agoMinute, hour, day are specifically allowed by CIPM to be used in SI. They just can't be used with prefixes. kWh is obviously inconsistent with SI conventions if commonly used; but 'kW⋅h' or 'kW h' is completely acceptable. As is 'W⋅h' A full list of acceptable non-SI units can be found in the brochure here under: "Non-SI units accepted for use with the SI units" https://www.bipm.org/en/publications/si-brochure https://www.bipm.org/en/publications/si-brochure
