I see now that watts and therefore kW are rates. So it's silly to add another rate to the end by appending "per hour". But what is the time component of the watt calculation? To me it's essentially instantaneous, even if that's wrong. Even if that breaks the math, it's still essentially true on a macro scale. And if it's instantaneous, or even just close like microseconds, then it doesn't hurt to apend another rate to the end, does it?
So why not use it? Batteries come with capacities rated in Wh and kWh, and it weirdly still makes sense to me because of my usage rate per hour example in my last comment.
And if we shouldn't use it, then what should we use?
Is this problem we're discussing, one that only occurs if you try to get really accurate with the numbers and times? Because for my uses it's always seemed to work well enough.
Not being argumentative, just trying to learn, thanks
Maybe it's regional? They don't ask for my card in Michigan.
But I do need to present it for a few things done at the SOS office. That's the DMV in Michigan.
Why make it a card then? If it's meant to be stored as a document then it should be the size of an envelope, or a standard A4 sheet.
I keep mine attached to the envelope sized paper it came on. But it shouldn't be a card shape, that encourages people to carry it. My grandpa always carried his.
Wait wait Wait, can you give me more on this kWh thing? I thought I understood this already.
A single kW is a unit of power, literally 1000 watts.
A kWh is a unit of energy, as in stored or delivered.
Draw 500 watts for 2 hours? That's a kWh.
Or have a battery that can hold 1 kWh, then assuming 100% efficiency you could draw 1000 watts from it for an hour before it was empty.
All of this is kW times hour, I would say?
But in my mind I would interchangeably say per hour as well, they feel the same.
Oh I didn't see that, good point. You might be right about the cut paper, but maybe it's folded instead? Look at the bottom left corner, the paper extends below the printed line, almost like it printed crooked? But I think more likely it's folded and that's the backside of the other half of the ruler? Like, is so low resolution that we can't tell it's a loop of paper there, maybe.
Those other two are so frequently used for scams that my bank has a heart attack every time I try to use them. No matter how many times I call them and tell them to unblock my card, because it was definitely me sending that money, they'll block it the very next time. I literally bought a checkbook (you have to buy those dumb things now?!) so I could more easily give people money... In 2023...
Google pay worked for me reasonably well for small transactions between friends and family. That's literally what I use it for 90% of the time. I'm super annoyed that they don't have a replacement for it.
But isn't wallet only for tap to pay? I use Google pay to send and receive money between my friends and family literally all the time.
Reading the email Google sent me, they only talk about tap to pay still working on wallet.
Yeah the extremeRate kit! I bought it but haven't installed it yet. I don't actually have a problem with the buttons as is, but it fell like an interesting change to make
I would also like to know the answer to this
