Why convert light years to miles?

Converting light years to miles helps express vast cosmic distances in units more familiar to everyday land measurements, easing comprehension.

Is the mile used here the same worldwide?

Yes, the mile referenced is the international statute mile defined by international agreement in 1959 and used mainly in countries with imperial or US customary units.

Can this conversion be used for precise astronomy?

Due to the immense difference in scale and rounding issues, converting to miles is mainly useful for general understanding rather than exact astronomical calculations.
