How to convert Gigaparsec to Megaparsec

Conversion factor and calculation steps from Gigaparsec (Gpc) to Megaparsec (Mpc).

Conversion logic

Each unit is defined via the base unit (meter (m)). The value is first converted to the base unit, then to the selected unit.

1 Gpc = 3.08567758e25 m

1 Mpc = 3.08567758e22 m

1 Gpc × 3.08567758e25 = 3.08567758e25 m

3.08567758e25 m ÷ 3.08567758e22 = 1000 Mpc
