ErkhyanToday in “a shitpost gave me perspective”:
The difference between one million and one billion is roughly one billion.
Zach Leatherman@erkhyan seems like people can understand 1K -> 1M better than 1M -> 1B
gizmomathboy, FC@zachleat @erkhyan couple similar analogies can start with:
A billion is to a million like 10 dollars to a penny, or a thousand dollars to one dollar.
Much easier for us but millionaires or billionaires to get our heads around and to communicate the the mind boggling number that a billion dollars is for one person to have.
And as always, billionaires shouldn't exist
Russell Phillips@gizmomathboy @zachleat @erkhyan I like a time-based one:
A million seconds is about 12 days.
A billion seconds is over 30 years.

I like millimeters.
5mm - tiny
5k mm - length of christmas lights
5MM mm - 5k running race
5B mm - slightly longer than the entire length of I-90
