Question

How many seconds are there in a year?

Answer 1

Compare days, hours, minutes, and seconds:

The units or terms in which time can be measured are seconds, minutes, hours, days, weeks, months, and years. We know,

$1$ minute $=60$ seconds

$1$ hour $=60$ minutes

Then, $1$ hour $=60\times 60$ seconds

$\Rightarrow$ $1$ hour $=3600$ seconds

Now, since, $1$ day $=24$ hours

$\Rightarrow$ $1$ day $=3600\times 24$ seconds

$\Rightarrow$ $1$ day $=86400$ seconds

Again, since, $1$ year $=365$ days

$\Rightarrow$ $1$ year $=86400\times 365$ seconds

$\Rightarrow$ $1$ year $=31,536,000$ seconds

Hence, In a year, there are $31,536,000$ seconds.
