What does a petameter measure?

A petameter is an SI unit of length equal to 10^15 metres, used for measuring extremely large distances such as those in astronomy.

Why use fingerbreadths as a unit?

Fingerbreadth is an informal length unit based on the width of an adult finger, helpful for rough, relatable measurements in everyday contexts.

Is this conversion accurate for scientific purposes?

No, because fingerbreadths vary between individuals and petameters measure vast distances, this conversion is intended mainly for rough estimation and educational use.
