How to convert chains (US survey) to microinches
1 chain (us survey) is equal to 792,001,584 microinches, and 1 microinch is equal to 1.262623737 × 10⁻⁹ chains (US survey). To convert, multiply by the conversion factor:
microinches = chains (US survey) × 792,001,584
microinches = chains (US survey) ÷ 1.262623737 × 10⁻⁹Example: convert 1 ch (US) to µin: 1 × 792,001,584 = 792,001,584 µin.
