How to convert feet (US survey) to microinches
1 foot (us survey) is equal to 12,000,024 microinches, and 1 microinch is equal to 8.333316667 × 10⁻⁸ feet (US survey). To convert, multiply by the conversion factor:
microinches = feet (US survey) × 12,000,024
microinches = feet (US survey) ÷ 8.333316667 × 10⁻⁸Example: convert 1 ft (US) to µin: 1 × 12,000,024 = 12,000,024 µin.
