## How to convert years to seconds (yr to s)

Converting years to seconds involves multiple steps because there are different lengths of years (such as standard years, leap years, etc.). Here's how you can generally convert standard years to seconds. 1 year is equal to 365 days (in a standard year) and 1 day is equal to 24 hours. Each hour has 60 minutes and each minute has 60 seconds. Here's the years to seconds conversion formula: Number of seconds = number of years × (365 × 24 × 60 × 60 × 1)### Step-by-Step Years to Seconds Conversion

**Multiply the number of years by the number of days in a year:**Number of Days = Number of Years × 365.**Multiply the number of days by the number of hours in a day:**Number of Hours = Number of Days × 24.**Multiply the number of hours by the number of minutes in an hour:**Number of Minutes = Number of Hours × 60.**Multiply the number of minutes by the number of seconds in a minute:**Number of Seconds = Number of Minutes × 60

## Example Conversion

Let's take a look at an example. The step-by-step process to convert 4 years to seconds is:

- Understand the conversion formula: s = yr × (365 × 24 × 60 × 60 × 1)
- Substitute the required value. In this case we substitute 4 for yr so the formula becomes: s = 4 × (365 × 24 × 60 × 60 × 1)
- Calculate the result using the provided values. In our example the result is: 4 × (365 × 24 × 60 × 60 × 1) = 126144000 s

In summary, 4 years is equal to 126144000 seconds.

## Converting seconds to years

In order to convert the other way around i.e. seconds to years, you would use the following formula: yr = s ÷ 3.154e+7. To convert seconds to years first substitute the second value into the above formula, and then execute the calculation. If we wanted to calculate 1 second in years we follow these steps:

yr = s ÷ 3.154e+7

yr = 1 ÷ 3.154e+7

yr = 0.0000000317057704502219403931515535828

Or in other words, 1 second is equal to 0.0000000317057704502219403931515535828 years.
