Conversion number between year (mean tropical) [a, y, or yr] and Metonic cycle; enneadecaeteris is 0.052628557694813. This means, that year (mean tropical) is smaller unit than Metonic cycle; enneadecaeteris.
Switch to reverse conversion:
from Metonic cycle; enneadecaeteris to year (mean tropical) conversion
| [a, y, or yr] |
Result in Metonic cycle; enneadecaeteris
?If conversion between year (mean tropical) to second and second to Metonic cycle; enneadecaeteris is exactly definied, high precision conversion from year (mean tropical) to Metonic cycle; enneadecaeteris is enabled.
Since definition contain rounded number(s) too, there is no sense for high precision calculation, but if you want, you can enable it. Keep in mind, that converted number will be inaccurate due this rounding error!

Definition of year (mean tropical) unit: ≈ 365.242190402 d. Tropical year is the length of time it takes for the Sun to return to the same position in the cycle of seasons, approximately 365.24219 days
Definition of Metonic cycle; enneadecaeteris unit: ≡ 6940 d. For astronomy and calendar studies, the Metonic cycle or Enneadecaeteris is a period of very close to 19 years that is nearly a common multiple of the solar year and the synodic month. ≡ 110 mo (hollow) + 125 mo (full) = 6940 d ≈ 19 a = 599.616 Ms
