How to convert chains (US survey) to femtometers
1 chain (us survey) is equal to 2.011684023 × 10¹⁶ femtometers, and 1 femtometer is equal to 4.970959596 × 10⁻¹⁷ chains (US survey). To convert, multiply by the conversion factor:
femtometers = chains (US survey) × 2.011684023 × 10¹⁶
femtometers = chains (US survey) ÷ 4.970959596 × 10⁻¹⁷Example: convert 1 ch (US) to fm: 1 × 2.011684023 × 10¹⁶ = 2.011684023 × 10¹⁶ fm.
