32500000000 KW/h per year

That's 32500000000 kWh/y
= 32500000000 * k * W * h / y
= 32500000000 * k * W * h / (365 * 24 * h)
= 32500000000 * k * W * h / 8760 / h
= 32500000000 / 8760 * k * W * h / h
= 3710046 * k * W * 1
= 3710046 kW

(You actually corrected yourself later when converting to mW.)

...... exactly as I intended

Since watt is joule per second, kwh per year is one kilojoule per second per hour per year.

Electricians have played us like fools

kWh is kilojoule per second times 3600 seconds or 3600 kilojoule. kWh/y is 3600 joule per year or 3600 kilojoule / (24*3600*365) ~0.1W

Even more cursed

[-] goostaf@lemmy.world 4 points 1 year ago

A kW/h would imply that the power changes by that amount every hour, while a kWh is the amount of energy spent in an hour

Oh yeah, lol, I blame Friday morning fatigue.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.
