Multiply the number of Foots by 9.8769×10-18 to get Parsecs. Formula: pc = ft × 9.8769×10-18. Example: 10 ft × 9.8769×10-18 = 9.8769×10-17 pc. To reverse, divide Parsecs by 9.8769×10-18 to get Foots.

To convert Foot to Parsec, multiply by 9.8769×10-18. Example: 10 ft = 9.8769×10-17 pc
To convert Parsec back to Foot, divide by 9.8769×10-18 (multiply by 1.0125×1017). Use the swap button above.
Start with 100 Foots = 9.8769×10-16 pc as your reference point. Scale up or down from there.
1 foot = 9.877×10⁻¹⁸ parsecs. US physics educators use foot-to-parsec conversion to demonstrate the extraordinary scale difference between everyday US measurement and the units of stellar astronomy.
Science communicators make stellar distances tangible for American audiences by converting from parsecs to feet: "The nearest star is 1.3 parsecs — that's 1.3×10¹⁷ feet, more than 100 quadrillion feet away."
NASA communications compare spacecraft distances (expressed in AU and light-minutes) with stellar distances in parsecs when contextualising deep space missions for American audiences familiar with feet and miles.
US university physics courses assign foot-to-parsec problems in dimensional analysis units — requiring students to chain conversion factors across US customary, SI, and astronomical unit systems simultaneously.
US science fiction writers convert parsec-scale interstellar distances to feet when building physically consistent scale descriptions of spacecraft sizes versus travel distances in hard SF settings.
Complete unit converters include foot-to-parsec for US researchers who encounter parsecs in astronomical literature and need to compare with foot-scale laboratory or engineering dimensions.
The Foot is a unit of Length measurement (symbol: ft). 1 ft = 9.8769×10-18 pc. Used in scientific and practical Length measurement applications.
The Parsec is a unit of Length measurement (symbol: pc). It is part of an internationally recognised measurement system used alongside the Foot.
The foot is one of humanity's oldest measurement units, used by ancient Egyptians, Greeks, and Romans — each with slightly different values. The English statute foot was standardised at 12 inches in 1305 under King Edward I. Its definition was refined multiple times over centuries, finally fixed as exactly 0.3048 metres under the International Yard and Pound Agreement of 1959, signed by the US, UK, Canada, Australia, and South Africa. Today the foot remains official in the US, UK aviation, and international aviation worldwide.
The parsec was introduced in 1913 by British astronomer Herbert Hall Turner as a practical unit for stellar parallax measurements. It equals the distance at which 1 astronomical unit subtends 1 arcsecond — approximately 3.086×10¹³ kilometres or 3.26 light-years. The name blends 'parallax' and 'arcsecond'. Professional astronomers strongly prefer parsecs over light-years because parallax directly yields distance in parsecs without any intermediate calculation.
Common use: Foot to Parsec conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
