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