How long to count to a million and a billion?

Counting to one million would take a significant amount of time, as it would involve saying a large number of digits. It would likely take several hours to count to one million out loud, depending on how quickly you can count.

Counting to one billion would take even longer, as it would involve saying even more digits. It would likely take several days to count to one billion out loud, depending on how quickly you can count.

It’s worth noting that these estimates are based on counting continuously without stopping, and that in practice it would be difficult to count for such a long period of time without taking breaks.
