What does one picometer equal in gigameters?

One picometer equals 1e-21 gigameters, reflecting the vast difference in scale between these units.

Why use picometers and gigameters for conversions?

They are used to bridge understanding between extremely small atomic dimensions and very large astronomical distances in various scientific fields.

Is this conversion useful for everyday measurements?

No, due to the extreme difference in magnitude, this conversion is mostly relevant in theoretical, scientific, or educational contexts.
