How many years older will you be 1.00 gigasecond from now? (Assume a 365-day year.)

In Physics there are many value which are very big when we write it into standard unit form. Like mass of Earth in kg or distance between two galaxies in km.

To make this quanity easy to write we use preface numbers which is multiple of 10^x. Here the value of x can be 3, 4, 9 etc.

1 giga means 10⁹, 1 mega means 10⁶

Given data:

The time given is 1 gigasecond.

In one day there are 24 hours. In each hour we have 60 min. Each 1 minutes are made of 60 seconds. So it can be said that in 1 day there are 24 x 3600 second.

Number of second in 1 year

= 3600 x 24 x 365

=31536000 Second

1 year old in 31536000 Second

The number of years in 1 gigasecond will be,

$$\begin{gathered} 1gigasecond=\frac{1000000000}{31536000} \\ 1gigasecond=31.7years \end{gathered}$$

Therefore, it is concluded thatyou will be 31.7 years old from now at 1 giga second.
