Calculation process of conversion value

1 parsec = `(3.085677581*10^16) / (299792458)` = 102927125.03795 light-second
1 light-second = `(299792458) / (3.085677581*10^16)` = 9.7156118917273 × 10^-9 parsec
? parsec × `(3.085677581*10^16 ("m"/"parsec")) / (299792458 ("m"/"light-second"))` = ? light-second

High precision conversion

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