About Astronomical Unit (AU) and Link (li) Units
What is an Astronomical Unit (AU)?
An Astronomical Unit (AU) represents the average distance between Earth and the Sun.
It’s defined as:
1 AU = 149,597,870.7 kilometers
This unit is used in astronomy to describe distances within our solar system, such as between planets and their orbits.
What is a Link (li)?
A Link is an old Imperial unit of length, primarily used in surveying and land measurement.
1 link = 0.66 feet = 7.92 inches = 0.201168 meters
It was commonly used alongside chains (1 chain = 100 links) in 17th–19th century land surveying systems.
What Does This Converter Do?
This tool converts Astronomical Units (AU) — a standard for cosmic distances — into Links (li), one of the smallest Earth-based surveying units.
It helps you visualize how immense astronomical distances would appear if measured using an old terrestrial standard.
How to Convert Between Astronomical Units and Links
To convert Astronomical Units (AU) to Links (li):
li = AU × 7.435984059 × 10¹¹
Or approximately:
1 AU ≈ 7.435984059 × 10¹¹ links
That means one Astronomical Unit equals about 743,598,405,900 links — highlighting the astonishing vastness of space when expressed in such small, human-scale units.
AU to Link Use Cases
Education: Compare cosmic distances with historic Earth-based units for classroom demonstrations.
STEM Learning: Blend astronomy, history, and measurement science in a creative way.
Public Outreach: Make cosmic distances relatable through familiar or historical units.
Visualization: Show the scale difference between ancient surveying units and modern astronomical measures.
Curiosity & Context: Offer fun and mind-expanding comparisons that put human measurements in perspective.
Why Convert Astronomical Units to Links?
While converting Astronomical Units (AU) to Links (li) isn’t used in scientific practice, it serves as a fascinating educational tool:
Perspective: See how incredibly vast cosmic distances appear when measured in small, historic units.
Historical Insight: Explore how early land surveyors measured the world compared to today’s cosmic scales.
Education: Encourage scale thinking in astronomy and mathematics.
Visualization: Transform abstract astronomical values into tangible, Earth-based equivalents.
Engagement: Use creative conversions to inspire curiosity about measurement systems and space.
Converting Astronomical Units to Links bridges ancient measurement systems and modern cosmic understanding, revealing how far human imagination — and science — has traveled.

Notes
1 AU ≈ 7.435984059 × 10¹¹ links
This table helps visualize astronomical distances — from fractions of an AU (like Mercury’s orbit) to thousands of AU (outer solar system and beyond) — expressed in Links, one of the smallest surveying units in human history.
It’s a fascinating perspective shift from cosmic immensity to Earth’s earliest measurement systems.
