Let's count to a billion

How much time needed to count 1 billion manually?

***Let's count to a billion. But first, let's see how long that will take. I can count pretty fast for a while. I mumble a little, like "sev-sen" for "seventy-seven." After a while (in the 100,000's), it takes me a lot longer than a second for each number. If it takes me a second for each number (which is a little unrealistic), then it would take me about 24 hours to count to 86,400. I can count to a million in less than half a month. It will take me more than 30 years to count to an American billion, and more than 30,000 years to count to a British billion.

***On the short scale at one per second, it would take about 31 1/2 years. On the long scale at the same speed, it would take 31000 years or so.

***It depends how fast you count...if you counted one number per second that would be
1 billion seconds
16,666,666 minutes
277,777 hours
11,574 days
31.7 years

Of course your speed would vary depending on number length and many other factors, but one second per number is a good average

In fact, if you took minimal time to sleep, lets say 4 hours a day, and, lets say 30 minutes to eat and other things and if you devoted your entire life to counting you could get to 1 billion in....

37.6 years

You could count to 1 trillion in 37,600 years

If you took every person on Earth and each person counted a different portion of the whole you could get to 1 billion in 2/13 of a second

1 trillion in 154 seconds
1 quadrillion in 43 hours
1 quintillion in 4.9 years
1 sextillion in 4878 years
