Just two years ago my car’s 50 kWh battery weighed around 350 kg, now you can get a 45 kWh battery that fits in the palm of your hand!

I love how we still needlessly use so many zeroes instead of just calling it Ah. Phones with 5000 mAh batteries. Or you know, we could just cal it 5Ah battery. Chinese are even further obsessed with this just adding zeroes because the more zeroes the better!
I’ve even seen people say “5k mAh”
Even better: we could use Wh instead, to not constantly correct for voltage!
But then you can’t inflate the numbers by putting a 3.7 volt battery in a power bank, listing the capacity in amp-hours and implying that you get that many amp-hours at the power bank’s 5V output voltage.
Uh-huh I remember getting quite angry when I figured this out back in the day :D
But you get more zeros with Ah 😂
Yeah but Americans are stupid and thought a 1/3lb burger was smaller than a 1/4lb burger. I fully expect they’d think 5Ah is smaller than 1000mAh.
I’ve wondered in the past why, for example, 1000 kilometers are still referred to as kilometers.
The moon is roughly 385 megameters away, or 0.4 gigameters!
Do we use MM for megameters and mm for millimeters? i think this might start to get confusing. We should probably clarify a few things before some tradie apprentice builds the galaxy’s largest bookshelf.
Yes, millimeters, or any other milli measurement (EG milliamps) starts with a lower case.
Kilo and up is capitalised.
Hehe, nice catch. Technically, under SI standard we could call that 1 megameters… It’s mostly we rarely address distances beyond 1000 kilometers in day to day life so kilometers still make some sense. Where under Imperial units, there isn’t any unit above mile. For batteries, we don’t really use anything less in phones anymore, only smartwatches and earbuds use capacities under 1000.
People don’t use megameters enough that you can rely on them knowing what it is nor have an intuition for it even if they technically know.
They should.
