How long does it take to count to a trillion adding 1every second?

Answer 1

A trillion seconds.

1 day = 86400 seconds.

Assuming 365.25 days in a year (it's actually slightly less), then 1 year = 31557600 seconds.

• In those countries that use the long scale (based on powers of a million) like Europe:

1 trillion seconds = (106)3 seconds = 1018 seconds

= 1018 ÷ (3.15576 x 107) years

≈ 3.1688 x 1010 years

or approx 311/2 thousand million years.

• In those countries that use the short scale (based on powers of a thousand plus one) like USA:

1 trillion seconds = (103)3+1 seconds = 1012 seconds

= 1012 ÷ (3.15576 x 107) years

≈ 31,688 years

or approx 311/2 thousand years.
