How many years are 5000 hours?

Answer 1

A common year has 365 days. It's actually not quite this exact for a year, but that exception is beyond the scope of this question.

Write out your conversion factors:

1 year = 365 days

1 day = 24 hours

Combine your conversion factors, in such a way that days cancels out (i.e., so you can go from years to days). Conversion factors can be written as a fraction, with one side of the conversion factor as the numerator, and the other as the denominator, e.g., (1 year / 365 days) or (365 days / 1 year). You can use fractions to cancel out units, just like anything else cancels out in a fraction (9 cookies / 9 cookies = 1 <--- the 9's cancelled, and the cookies cancelled out)

( 1 year / 365 days ) x ( 1 day / 24 hours )

( 1 year ) / ( 365 x 24 hours )

1 year / 8760 hours --> 1 year = 8760 hours

Now use your derived conversion factor to convert the 5000 hours. Once again, make sure units cancel out (in this case you want hours to cancel out).

5000 hours x ( 1 year / 8760 hours ) = ( 5000 / 8760 ) years

5000 hours ~= 0.571 years (~= means approximately equal to)

The answer is 5000 hours is approximately equal to 0.571 common years.
