fwiw there's a comment by @Mycatiskai@lemmy.ca as a top-level reply to the post that I think was intended as a reply to you.

kWh are a metric unit (even if they're not SI), and are extremely common in discussions of household electricity. I wish it weren't the case, the same way I wish countries other than Australia used kilojoules for measuring energy in food instead of (kilo)Calories. But they don't.
