Calculation process of conversion value

1 light-year = `(9460730472580800) / (3.085677581*10^16)` = 0.30660139383437 parsec
1 parsec = `(3.085677581*10^16) / (9460730472580800)` = 3.2615637766481 light-year
? light-year × `(9460730472580800 ("m"/"light-year")) / (3.085677581*10^16 ("m"/"parsec"))` = ? parsec

High precision conversion

If conversion between light-year to metre and metre to parsec is exactly definied, high precision conversion from light-year to parsec 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!
