Learn how to convert years to seconds

Converting seconds to years is quite straightforward, so let's dive in and see how we can do it in situations where we can't take assistance from a tool.

🙋 Generally, people calculate a year with 365 days, but it's actually 365.25 days, and that's exactly why we have a leap year every 4 years.

Now, let's calculate this with better precision:

  • 1 year = 31,557,600 seconds.

Inversely:

  • 1 second = 0.00000003169 years.

Thus, to convert seconds into years, we can use the following formula:

  • Years = seconds × 0.00000003169

For instance, to convert 10,000,000 seconds into years, multiply it by 0.00000003169, which is ≈ 0.3169 years.

And, to convert years to seconds, we can use:

  • Seconds = years × 31557600

For instance, to convert two years into seconds, multiply it by 31557600, which is = 126,230,400 seconds.

How can I find the number of seconds in a year?

There are 31,557,600 seconds in a year.

You can find this number by multiplying the total number of days in a year with 24 hours, 60 minutes, and 60 seconds as follows:

1 Year = 365.25 × 24 × 60 × 60

1 year = 31,557,600 seconds

How many years are there in a trillion seconds?

There are approximately 31,688 years in one trillion seconds.

To calculate this, multiply the total number of given seconds, which is one trillion, with the number of years in one second, that is 0.00000003169, i.e.:

Years = seconds × 0.00000003169

1,000,000,000,000 × 0.00000003169 = 31,688

How can I convert 100 years into seconds?

To convert 100 years into seconds:

  1. Multiply the number of years by 31,557,600 seconds, as 1 year is equal to 365.25 days, which is equal to 31,557,600 seconds, i.e.,

    Seconds = years × 31557600

  2. Placing the values, we get:

    100 × 31557600 = 3155760000 seconds
