Calculation process of conversion value

1 year (Gregorian) = (exactly) `(31556952) / (315569520)` = 0.1 decade
1 decade = (exactly) `(315569520) / (31556952)` = 10 year (Gregorian)
? year (Gregorian) × `(31556952 ("s"/"year (Gregorian)")) / (315569520 ("s"/"decade"))` = ? decade

High precision conversion

If conversion between year (Gregorian) to second and second to decade is exactly definied, high precision conversion from year (Gregorian) to decade is enabled.

Convert Year (Gregorian) to other unit:

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.

Convert Decade to other unit:

decade

Definition of decade unit: ≡ 10 years (Gregorian). = 365.2425 × 10 × 86400 seconds
