A parsec is an astronomical unit of length representing the distance at which one astronomical unit subtends an angle of one arcsecond, commonly used for measuring stellar distances.

Why convert parsecs to petameters?

Converting parsecs to petameters provides distances in SI units, facilitating engineering and observational calculations where metric units are preferred.

Is the petameter suitable for small distances?

No, petameters are designed for extremely large distances and are not practical for small or planetary scale measurements.
