Comment on Battery tech really does move fast

  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.

    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!

      To avoid confusion, just use mebimeters (1 Mim = 2^20 m)

        I only use parsecs to measure distance

      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.

  I’ve even seen people say “5k mAh”
