Chains to Astronomical Units Converter
This Chains to Astronomical Units Converter lets you convert Chains (ch) into Astronomical units (AU) in one step. Enter a value in chains and you'll instantly see the equivalent in astronomical units, worked out with the formula AU = ch x 1.3447250222124986e-10. It's handy whenever you need a quick, precise chains-to-astronomical units conversion without doing the arithmetic by hand.
- Conversion constants are fixed and do not vary by region.
Formula
AU = ch x 1.3447250222124986e-10
- To convert chains to astronomical units, multiply your value by the fixed factor 0.000000000134 (so 1 ch = 0.000000000134 AU).
- 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.
Example
Inputs
- Chains (ch): 10
Start with 10 ch. Multiply by 0.000000000134 to get 0.000000001345 AU.
Frequently asked questions
How do I convert chains to astronomical units?
Multiply the number of chains by 0.000000000134. For example, 10 ch equals 0.000000001345 AU.
Are these conversion factors accurate?
Yes. The calculator uses internationally accepted definitions for each unit, so the conversion factor is exact.
Why can tiny differences appear after conversion?
Very small differences are only a display effect from rounding the output. The underlying calculation keeps full precision.
