How to convert chains to microinches
1 chain is equal to 792,000,000 microinches, and 1 microinch is equal to 1.262626263 × 10⁻⁹ chains. To convert, multiply by the conversion factor:
microinches = chains × 792,000,000
microinches = chains ÷ 1.262626263 × 10⁻⁹Example: convert 1 ch to µin: 1 × 792,000,000 = 792,000,000 µin.
