How to convert chains to astronomical units
1 chain is equal to 1.344725022 × 10⁻¹⁰ astronomical units, and 1 astronomical unit is equal to 7,436,464,582 chains. To convert, multiply by the conversion factor:
astronomical units = chains × 1.344725022 × 10⁻¹⁰
astronomical units = chains ÷ 7,436,464,582Example: convert 1 ch to au: 1 × 1.344725022 × 10⁻¹⁰ = 1.344725022 × 10⁻¹⁰ au.
