How to estimate it
Fermi’s official “Napkin math”
Most numbers in that range take about two words to say, like fifty three or four hundred twelve. Multiply two words by a million and you get roughly eight million words total. A voice assistant talks about as fast as a person, around 150 words a minute. Divide it out.
- Words to say, roughly
- ≈ 8 million
- Speaking pace
- ≈ 150 words/min
- 8M ÷ 150 ÷ 60 ÷ 24
- ≈ 37 days
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Words to say 1 to 1,000,000
- = 8,019,002
- Average speaking pace
- ≈ 150 words/min
- 8,019,002 ÷ 150 ÷ 60 ÷ 24
- ≈ 37 days
Reference cited by Fermi: Arithmetic: word count for numbers 1-1,000,000 spoken aloud (American English, no 'and') at an average 150 wpm speaking pace

Compare by ratio: divide the larger number by the smaller one. The closer to 1×, the better.
