How do you normally deal with this question – how many years is a trillion seconds?

Online Unit Conversion-Trillion sec to Years

In a trillion seconds there are 31,710 years.

Nowadays people use seconds, minutes, hours and days to measure time, which makes everything easier. Also, with International System of Units, millisecond, microsecond, nanosecond and picosecond are members of this time unit family. So how many years is a trillion seconds? One trillion seconds is how many years?

In SI Unit of time, there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, 7 days in a week and 365 days in a year ( which usually means a common year with exactly 365 days). So let’s do it step by step: A trillion seconds is equal to how many years? How many is a trillion seconds in years?

So,
. 1 minute = 60 seconds
. 1 hour = 60 minutes
1 hour = 60s x 60m = 3,600 seconds (PS: minute= m, second= s)

Then,
. 1 trillion seconds = 1,000,000,000,000 s
. 1 day = 24 hours
1 trillion seconds = 1,000,000,000,000s ÷ 3600s ÷ 24h = 11,574,074 days 
(PS: second= s, hour= h, days =d)

At last,
. 1 year = 365 days
11,574,074 days = 11,574d ÷ 365d = 31,710 years (PS: second= s, hour= h, day= d)

1,000,000,000,000 seconds = 1,000,000,000,000s ÷ 3600s ÷ 24h ÷ 365d = 31,710 years 
(PS: minute= m, second= s, hour= h, day= d)

1,000,000,000,000 seconds = 31,710 years
