As an American I appreciate how they included both metric (Joules) and imperial (hours running a microwave) measurements

AI, in this case, refers to LLMs, GPT technology, and anything listed as "AI" meant to increase market valuations.

I only know how long bald eagles burn for.
How do I convert microwave hours to bald eagle burn time (in number of football games including all dead ball times and the halftime shows)?
Truly every time period of human civilization had something in it that would make future generations shake their heads in disbelief.
"How could they use gigawatthours for crypto farms and useless AI applications while fully aware of a climate crisis caused by fossil fuels?", a student might ask his history teacher some day. "Because they were dumb as fuck.", the teacher might answer.
Did you see the stockarket?!

They definitely need to make measures like this widely available.

3.4 megajoules = 944 watt hours
Microwaves are typically rated at 1200-1500 watts, sometimes more. Do they actually use that much? I'm not sure, stuff typically uses less than the rated power on the label.
Thank you for the conversion. We have a common unit for electrical energy already, and megajoules is not it. Trying to make it sound like a bigger number by changing the unit only muddies the waters and honestly makes me slightly less sympathetic to the issue.
Seriously?
Joules are the SI unit for energy measurement. 1 Joule = 1 Watt second, so 3600 Joules = 1 Watt Hour
They teach this in middle school.
Ok, but when it comes to electrical energy nobody uses "watt seconds" in the real world. Devices use hundreds of watts, and run for minutes and hours. Dividing by 3.6 million isn't exactly easy mental math to get the unit (kWh) we all see on our electric bills.
Yeah, that's true, but joules typically isn't used today. When people talk about energy consumption it's almost always in watts or watt-hours. I've seen/heard people use joules less than 5 times since college.
Ive seen more 700-1200 watt microwaves.
