Astronomical Units to Chains Converter
This Astronomical Units to Chains Converter lets you convert Astronomical units (AU) into Chains (ch) in one step. Enter a value in astronomical units and you'll instantly see the equivalent in chains, worked out with the formula ch = AU x 7436464581.842042. It's handy whenever you need a quick, precise astronomical units-to-chains conversion without doing the arithmetic by hand.
- Conversion constants are fixed and do not vary by region.
Formula
ch = AU x 7436464581.842042
- To convert astronomical units to chains, multiply your value by the fixed factor 7,436,464,581.842042 (so 1 AU = 7,436,464,581.842042 ch).
- The factor comes from the internationally agreed definitions of each unit, so it never changes.
- Displayed results are rounded for readability, but the full-precision value is used in the calculation.
