What is a furlong (US survey)?

A furlong (US survey) is a historical US length unit defined as 660 US survey feet, commonly used in old land surveys and legal descriptions.

What does one terameter represent?

One terameter equals 10^12 metres and is used to measure very large astronomical distances such as planetary orbits.

Why convert furlongs to terameters?

Converting furlongs to terameters helps translate traditional land measurement units into large-scale SI units suitable for astronomy and scientific study.

Tips & Best Practices

Use this converter primarily for scientific or astronomical applications due to scale differences
Be aware that furlong (US survey) is a historical non-SI unit, limiting everyday usefulness
Refer to terameter values when dealing with very large distances like planetary orbits
Double-check units when interpreting historical land measurements to avoid confusion

Limitations

Resulting values are very small decimals because of the scale difference
Not practical for daily use outside specialized scientific or astronomical fields
The furlong (US survey) is not an SI unit and is largely historical
