How many seconds are there in 1 year (show work if possible)?

31,536,000 seconds

Step-by-step explanation: In this problem, we are asked to convert 1 year into seconds. Unfortunately, we don't have a conversion factor for years and seconds but we do have conversion factors we can work with.

Conversion factors

60 seconds = 1 minute

60 minutes = 1 hour

24 hours = 1 day

365 days = 1 year

We can convert 1 year into seconds by using all four of these conversion factors. Also, remember that when we go from a larger unit "years" to a smaller unit "seconds" we multiply.

Let's first convert 1 year to days by multiplying 1 by the conversion factor which is 365 to get 365 days.

Next, we convert days to hours by multiplying 365 by the conversion factor which is 24 to get 8,760 hours.

Then, we convert hours to minutes by multiplying 8,760 by the conversion factor which is 60 to get 525,600 minutes.

Finally, we convert minutes to seconds by multiplying 525,600 by the conversion factor which is 60 to get 31,536,000 seconds.

Therefore, 1 year = 31,536,000 seconds.
