What is a furlong (US survey)?

It is an historical US land length unit equal to 660 US survey feet, or about 201.1684 meters, traditionally used in cadastral surveys and land descriptions.

What does Earth's distance from the sun represent in this tool?

It represents the astronomical unit (AU), the average distance between Earth and the Sun, standardized as exactly 149,597,870,700 meters.

Is this conversion practical for measurement purposes?

No, due to the large difference in scale, the conversion mainly serves conceptual or comparison-based applications between terrestrial and astronomical distances.

What Is This Tool?

This converter translates lengths measured in furlong (US survey), a historical land surveying unit, into Earth's distance from the sun, known as the astronomical unit (AU). It bridges terrestrial measurements and astronomical distances for diverse applications.

How to Use This Tool?

Input the length value in furlong (US survey) you wish to convert.
Select furlong (US survey) as the from-unit if required.
Choose Earth's distance from sun (astronomical unit) as the to-unit.
Click convert to see the equivalent value in AU.

Key Features

Converts furlong (US survey) — a traditional US land measurement unit — to the astronomical unit (AU).
Provides exact conversion based on standardized definitions.
Useful for relating old land survey data to astronomical scales.
Browser-based and straightforward to operate.

Examples

1 furlong (US survey) equals approximately 1.3447 × 10⁻⁹ Earth's distance from the sun.
10 furlongs (US survey) convert to roughly 1.3447 × 10⁻⁸ AU.

Common Use Cases

Interpreting historical U.S. land parcel boundaries in astronomical terms.
Converting traditional British-American units for scientific or space research purposes.
Supporting spacecraft trajectory planning with terrestrial to astronomical unit conversions.
Analyzing and comparing distances in solar system scale models.

Tips & Best Practices

Use this tool mainly for conceptual understanding or educational comparisons between land and space distances.
Remember that the furlong is a much smaller unit compared to the astronomical unit, so expect very small numeric results.
Be aware of the standard AU defined as a constant, acknowledging minor orbital variations in actual Earth-Sun distance.

Limitations

Furlong (US survey) represents a small terrestrial length, while Earth's distance from the sun represents an extremely large scale, resulting in tiny converted values.
The astronomical unit is a defined constant; actual Earth-Sun distance varies due to elliptical orbit, so this conversion is approximate for practical use.
Primarily serves conceptual or comparative purposes rather than direct measurement accuracy.
