What does petameter measure?

Petameter (Pm) is an SI unit of length equal to 10^15 metres, used for measuring extremely large distances, especially in astronomy.

What is the equivalent of 1 Petameter in Megameters?

1 Petameter equals 1,000,000,000 Megameters, converting extremely large distances into more familiar units.

Why convert petameters to megameters?

Converting helps relate astronomical scales to planetary and terrestrial distances, making large measurements more comprehensible.
