Conversion number between year (mean tropical) [a, y, or yr] and octaeteris is 0.12499732731075. This means, that year (mean tropical) is smaller unit than octaeteris.
Switch to reverse conversion:
from octaeteris to year (mean tropical) conversion
| [a, y, or yr] |
Result in octaeteris
?If conversion between year (mean tropical) to second and second to octaeteris is exactly definied, high precision conversion from year (mean tropical) to octaeteris 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!
