What is a furlong (US survey)?

It is a historical length unit used in US land surveying, equal to 660 US survey feet or roughly 201.1684 meters.

Why use petameters for distance?

Petameters measure extremely large distances, suitable for astronomical and astrophysical scales beyond the Solar System.

Can I use this tool for legal land descriptions?

Yes, it can assist in interpreting and converting historical land measurements, but verify accuracy due to historical unit variations.

Initiate the conversion to get the equivalent value in petameters.

Key Features

Converts furlong (US survey) to petameter using defined conversion factors.
Supports understanding of both traditional land measurement and astronomical distance units.
Accessible browser-based interface for quick and easy conversions.

Examples

5 furlongs (US survey) convert to approximately 1.005842011684e-12 petameters.
10 furlongs (US survey) convert to approximately 2.011684023368e-12 petameters.

Common Use Cases

Transforming historical land survey data or legal descriptions into metric or large scale units.
Interpreting distances from old maps or cadastral surveys for scientific or legal analysis.
Converting traditional race distances into astronomical units for astrophysical research.

Tips & Best Practices

Use this conversion for bridging between customary surveying units and extremely large SI units carefully.
Verify historical definitions of survey units to ensure accuracy before applying conversions.
Consider the scale difference when interpreting results—petameter is best for very large distances.

Limitations

Furlongs are not practical for directly measuring astronomical distances due to scale disparity.
Converting typical furlong measures to petameters might lead to precision loss on extremely large scale units.
Historical variations in survey unit definitions require caution for legal or scientific use.
