    Here we need to convert year into seconds.

    so lets do it step by step

    first lets convert year to hours

    1 year has 365 days - 365 days per year

    and a day has 24 hours - 24 hours per day

    therefore 1 year will have - 1 year x 365 days per year x 24 hours per day

    = 8760 hours

    next convert hours to seconds

    1 hour has 60 minutes - 60 minutes per hour

    and 1 minute has 60 seconds - 60 seconds per minute

    since 1 year has 8760 hours

    8760 hours will have - 8760 hours x 60 minutes per hour x 60 seconds per minute

    = 31 536 000 seconds = 3.15 x 10⁷ s

    answer is 3.15 x 10⁷ s in one year
