Most people can’t handle dealing with million/billion/… numbers, which leads to mistakes like “Elon Musk has 600 billion dollars, he could give every person on Earth a million dollars and still be a billionaire”.
Doing that with scientific notation would be clearer:
600 billion dollars=6e11
divided by 1 million dollars per person (1e6)
(6/1)e(11-6)=6e5=600 000 people Elon can give money to before running out (and that’s if we assume he has that much in cash and not assets and stuff)


That’s probably better, yeah. (also, I fixed my mistake, thanks for pointing it out)
Hmmh. I mean your original calculation should have worked as well, it was just a bit complicated so mistakes happen. I’m still more happy with what I proposed. It’s the same thing as engineering notation. Which is scientific notation, just skip the odd exponents, that’s overly complicated and a completely unnecessary extra step. The exponent notation will deal nicely with this anyway. 600 billions is 600e9 (instead of 6e11) it’s the same number just that nobody has a clue what 10^11 is and everyone knows how many zeroes after a billion. So you skip all unnecessary conversions and just copy the number. It’s 600e9/8e9 for the old example, which is 75e0 = 75. Or 600e9/1e6 in the new example, which is 600/1 e (9-6) = 600e3. You also immediately know it’s 600k.
Engineers use it because it’s really useful for real-world numbers. Also why it’s in the metric system. And the less conversions and operations, the less mistakes.
TIL. I like this
