How to convert inches (US survey) to microinches
1 inch (us survey) is equal to 1,000,002 microinches, and 1 microinch is equal to 9.99998 × 10⁻⁷ inches (US survey). To convert, multiply by the conversion factor:
microinches = inches (US survey) × 1,000,002
microinches = inches (US survey) ÷ 9.99998 × 10⁻⁷Example: convert 1 in (US) to µin: 1 × 1,000,002 = 1,000,002 µin.
