⚡ Astronomical Units to Chains: the quick answer

1 AU = 7,436,460,000 ch 1 astronomical unit equals 7,436,460,000 chains

To convert astronomical units to chains, multiply the value by 7,436,460,000. To go the other way, multiply chains by 1.34473 × 10⁻¹⁰ to get astronomical units.

↔ Convert chains to astronomical units instead

🧮 Formula

Astronomical Units to Chains
ch = AU × 7,436,460,000
Chains to Astronomical Units
AU = ch × 1.34473 × 10⁻¹⁰

Where

  • AU = the length in astronomical units
  • ch = the length in chains
Every unit here is defined by its length in meters, so the conversion factor is (meters per astronomical unit) ÷ (meters per chain).
