How to convert chains (US survey) to megaparsecs
1 chain (us survey) is equal to 6.51942392 × 10⁻²² megaparsecs, and 1 megaparsec is equal to 1.533877858 × 10²¹ chains (US survey). To convert, multiply by the conversion factor:
megaparsecs = chains (US survey) × 6.51942392 × 10⁻²²
megaparsecs = chains (US survey) ÷ 1.533877858 × 10²¹Example: convert 1 ch (US) to Mpc: 1 × 6.51942392 × 10⁻²² = 6.51942392 × 10⁻²² Mpc.
