### Calculation process of conversion value

• 1 sigma = (exactly) (0.000001) / (31556952) = 3.1688738506811 × 10-14 year (Gregorian)
• 1 year (Gregorian) = (exactly) (31556952) / (0.000001) = 31556952000000 sigma
• ? sigma × (0.000001  ("s"/"sigma")) / (31556952  ("s"/"year (Gregorian)")) = ? year (Gregorian)

## Details about sigma and year (Gregorian) units:

Convert Sigma to other unit:

### sigma

Definition of sigma unit: ≡ 10−6 s. Unit of time equal to one microsecond (1 μs) or 10-6 seconds.

Convert Year (Gregorian) to other unit:

### year (Gregorian)

Definition of year (Gregorian) unit: = 365.2425 d average. As the common year has 365 days, the Gregorian calendar with leap years compensate the deviation from the real, astronomical year. According to this calendar, every 4th year is a leap year, except for every 100th. But every 400th is a leap year. This means that there are 97 leap years in 400 year period. So according to Gregorian's calendar, one year has 365 + 97/400 days (average). This is not a perfect approach, but in 1000 year period, the defiation is only 0.3 days compared to the astronomical year. In the year 1582 Gregorian replaced the Julian calendar.
