A gigameter (Gm) is an SI derived unit of length equal to one billion metres, commonly used to express very large distances such as those in astronomy.

What does a picometer measure?

A picometer (pm) is an SI unit equal to one trillionth of a meter, used to describe extremely small distances like atomic bond lengths.

When would I convert gigameters to picometers?

This conversion is useful for bridging large astronomical distances and atomic-scale measurements, facilitating scientific analysis across scales.
