# Astronomical Units to Yards (au to yd) Source: https://www.unitconvertercalculator.com/length/astronomical-units-to-yards/ **1 au = 163602220800.52 yd** One astronomical unit equals approximately 1.636 x 1011 yards, or about 163.6 billion yards. This conversion expresses the Earth-Sun distance in the American sports and fabric unit. A football field (100 yards) is an incomprehensibly tiny fraction of 1 AU. ## Formula Convert Astronomical Units to Yards ## Conversion Table | Astronomical Units (au) | Yards (yd) | |---|---| | 1.0E-10 au | 16.360222080052 yd | | 1.0E-9 au | 163.60222080052 yd | | 1.0E-8 au | 1636.0222080052 yd | | 1.0E-7 au | 16360.222080052 yd | | 1.0E-6 au | 163602.22080052 yd | | 1.0E-5 au | 1636022.2080052 yd | | 0.0001 au | 16360222.080052 yd | | 0.001 au | 163602220.80052 yd | | 0.01 au | 1636022208.0052 yd | | 0.1 au | 16360222080.052 yd | | 1 au | 163602220800.52 yd | ## Units ### Astronomical Unit (au) Exactly 149,597,870,700 meters by IAU 2012 definition. Roughly the average distance from the Earth to the Sun. Used for distances within our solar system. ### Yard (yd) An imperial unit of length equal to 3 feet or 0.9144 meters. Used in American football, golf, and fabric measurement. ## Background The Earth-Sun distance is about 163.6 billion yards. A 100-yard football field is 6.11 x 10-10 AU long. You would need about 1.636 billion football fields placed end to end to bridge the Earth-Sun gap. The yard works beautifully for sports but is absurdly impractical for astronomy. ## Good to Know 'How many football fields to the Sun?' is one of the most popular ways to visualize astronomical distances for American audiences. The answer (about 1.6 billion) is itself hard to grasp, which is precisely the point. ## FAQ ### How many yards are in 1 AU? One AU contains approximately 1.636 x 1011 yards (about 163.6 billion yards). Since 1 AU = 149,597,870,700 m and 1 yard = 0.9144 m, divide accordingly. ### How many football fields is 1 AU? About 1.636 billion football fields (100 yards each) placed end to end would span 1 AU. This vivid comparison helps illustrate the enormous Earth-Sun distance. ### Is this conversion used anywhere? Only in educational or illustrative contexts. 'How many football fields to the Sun?' is a popular science visualization. No scientific or engineering application uses yards for astronomical distances. ## Non-Frequently Asked Questions ### How many football fields is it to the Sun? 1 AU is about 163.5 million yards. A football field is 100 yards. So about 1.635 million football fields end-to-end to reach the Sun. The NFL would need a much bigger TV deal. ## Related Articles - [Why We Measure: The Deepest Urge in Human Civilisation](https://www.unitconvertercalculator.com/blog/why-we-measure) - [The Map Is Not the Territory: Why Every Measurement Is Wrong](https://www.unitconvertercalculator.com/blog/the-map-is-not-the-territory) - [Zero: The Most Dangerous Number in Measurement](https://www.unitconvertercalculator.com/blog/zero-the-most-dangerous-number-in-measurement) - [The Body as a Ruler: Every Measurement Unit That Came From Us](https://www.unitconvertercalculator.com/blog/the-body-as-a-ruler) - [The Speed of Everything: How We Measure From Glaciers to Light](https://www.unitconvertercalculator.com/blog/the-speed-of-everything) - [15 Obscure Measurement Units You've Never Heard Of (But Still Need)](https://www.unitconvertercalculator.com/blog/obscure-measurement-units-guide) - [When Measurements Go Wrong - Disasters, Blunders and Happy Accidents](https://www.unitconvertercalculator.com/blog/when-measurements-go-wrong) - [The Surprising Stories Behind Everyday Units of Measurement](https://www.unitconvertercalculator.com/blog/stories-behind-measurement-units) - [Metric vs. Imperial - The Complete Guide to the World's Two Measurement Systems](https://www.unitconvertercalculator.com/blog/metric-vs-imperial-complete-guide) - [Length & Distance Conversion Guide - Meters, Feet, Miles & Kilometers](https://www.unitconvertercalculator.com/blog/length-and-distance-guide) ## See Also - [Yards to Astronomical Units](https://www.unitconvertercalculator.com/length/yards-to-astronomical-units/)
