### Calculation process of conversion value

• 1 year (common) = (31536000) / (2.418884326509*10^-17) = 1.3037415495396 × 10+24 atomic unit of time
• 1 atomic unit of time = (2.418884326509*10^-17) / (31536000) = 7.6702318826389 × 10-25 year (common)
• ? year (common) × (31536000  ("s"/"year (common)")) / (2.418884326509*10^-17  ("s"/"atomic unit of time")) = ? atomic unit of time

### High precision conversion

If conversion between year (common) to second and second to atomic unit of time is exactly definied, high precision conversion from year (common) to atomic unit of time 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!
