But familiarity gets more remote as you need larger and larger (or, smaller and smaller) multipliers. It's far more illustrative to say "the volume of a typical gas tank" than "the internal volume of hundred million poppy seeds", even though the volumes are in the same ballpark. For example, https://en.wikipedia.org/wiki/Orders_of_magnitude_(voltage) https://en.wikipedia.org/wiki/Orders_of_magnitude_(voltage) says that high voltage substations are in 100 kV range and 25.5MV is "The largest man-made DC voltage – produced in a Van de Graaff generator at Oak Ridge National Laboratory" and gives me much better color than a "comparison" with 100 million batteries. (By the way, 100 million batteries stacked together is a bit over the length of one marathon - how many readers could easily tell you that just from the description alone? Much better to measure many lengths in marathons than 10^8's of battery lengths!)
- BobaFloutist 2y agoThat's fair but the average person kinda knows how much (work/light/heat) a single AA battery can do/produce, but not what a substation can do.
- samplatt 2y agoI would posit that no person on earth has personal experience of 100 million AA batteries in a single circuit.
- lazide 2y agoHow many have personal experience with 150 MV?
- varjag 2y agoApproximately the same but now you at least use units that make sense.
- lazide 2y agoCan you convert that to marathons per fortnight for me?
- Denvercoder9 2y agoIt's about 102 kiloTesla marathons squared per forthnight. Dimensions are weird.

- benjijay 2y agoWell, now I have a goal!
- varjag 2y agoHowever voltage does not tell you how much work a battery can produce.
- lazide 2y agoThey need to write for an (average) 6th grade reading level - maximum. So think 4th grade most of the time. How many 4th graders have any clue what a mega volt is? How many do you think have personal experience with 150 mega volts?
- SAI_Peregrinus 2y agoHow many have experience with AA batteries these days? How many with 100 million of anything, enough to get an idea of how much bigger that is than one of the thing? Probably all about the same numbers.
- LorenPechtel 2y agoPlenty of AA batteries around. And AAA for that matter. At the low end the fancy battery packs can easily be more expensive than what they're powering. Li-Ion is choose only one: cheap or safe.
