It's 1 kwh not kw/h.  (power = energy * time.    kW * hours = kWh).

Yes all electrical power used by a computer gets converted into heat.

Technically it isn't exactly 100%.  Some gets converted into infared light and if your computer is near a window could "escape" your house.
However for all intents & purposes. 1kWh load = 1kWh thermal energy added to your house.  1 kWh ~= 3400 BTU if that helps you think about it in  easier terms.

Thank you.

Gop back to school, whatever school you went to return your certificate saying you slept in basics physics.

Per basic physics it means 1kwh heat - other energy output which is sound (VERY little) and anything else.

People learn this in 5th grade here. Energy preservation.

ESPECIALLY: YOU CAN NEVER HAVE MORE HEAT THAN THE ENERGY YOU USE. This is when you burn something the inner energy (exothermic reaction) bu a computer does not use up any fuels, you know.

Maybe some of those energy got converted by E=mc^2 to become matter

Ye must know everything in the world then. Wow I've never met anyone that knows everything before. Can I PM you with any questions or better yet would you be able to create your own blog I can subscribe to?

I work in ERP and have many questions regarding Navision and SAP. I've only 4 years experience - but now that I've met ye? I'll even pay you.

this is not true for all things the use electricity
motor's for example have some heat loss and some is the work performed
transformers also have some lost to heat, some to emf generating it's field, the rest is load on its secondary side

guess you missed something in physics class too

Everything else is negligible.

My computer is kinda noisy, and if i was deaf i could still tell if it was running by feeling the desk, all that noise and vibration is still nothing compared to the heat it produces?

(I dont always get new reply notifications, pls send a pm when you think it has happened)

Wanna gimme some BTC/BCH for any or no reason? 1FmvtS66LFh6ycrXDwKRQTexGJw4UWiqDX

The more you believe in Bitcoin, and the more you show you do to other people, the faster the real value will soar!

Most of that becomes heat anyways.  It is simply indirect.  Instead of electricity -> heat it is electricity -> vibration -> heat.

Ah, right, everything eventually turns to heat.

But eventually the motor work will become heat (when a car stop), same for the emf or the load on the secondary side.
