Number of days in a year are 365

Number of hours in a day is 24

So the number of hours in a years is $24\times 365\phantom{\rule{1ex}{0ex}}\text{}\phantom{\rule{1ex}{0ex}}\frac{\text{hours}}{\text{year}}$

Number of minutes in an hour is 60

So the number of minutes in a year is $60\times 24\times 356\phantom{\rule{1ex}{0ex}}\text{}\phantom{\rule{1ex}{0ex}}\frac{\text{minutes}}{\text{year}}$

The number of seconds in a minute is 60

Thus the number of seconds in a year is:

$60\times 60\times 24\times 356\phantom{\rule{1ex}{0ex}}\text{}\phantom{\rule{1ex}{0ex}}\frac{\text{seconds}}{\text{year}}$

$31536000$

$\to 3.1536\times {10}^{7}$
