How to convert fathoms (US survey) to microinches
1 fathom (us survey) is equal to 72,000,144 microinches, and 1 microinch is equal to 1.388886111 × 10⁻⁸ fathoms (US survey). To convert, multiply by the conversion factor:
microinches = fathoms (US survey) × 72,000,144
microinches = fathoms (US survey) ÷ 1.388886111 × 10⁻⁸Example: convert 1 ftm (US) to µin: 1 × 72,000,144 = 72,000,144 µin.
