How to convert feet (US survey) to parsecs
1 foot (us survey) is equal to 9.87791503 × 10⁻¹⁸ parsecs, and 1 parsec is equal to 1.012359387 × 10¹⁷ feet (US survey). To convert, multiply by the conversion factor:
parsecs = feet (US survey) × 9.87791503 × 10⁻¹⁸
parsecs = feet (US survey) ÷ 1.012359387 × 10¹⁷Example: convert 1 ft (US) to pc: 1 × 9.87791503 × 10⁻¹⁸ = 9.87791503 × 10⁻¹⁸ pc.
