What is a petameter used for?

A petameter is used to measure extremely large distances in astronomy, such as between nearby stars or large interstellar structures.

Why convert petameters to US survey links?

This conversion helps reconcile modern astronomical measurements with historical land survey records and cadastral data in the United States.

Is the US survey link still commonly used?

The US survey link is largely obsolete today but remains important for interpreting historical land surveying documents.

What Is This Tool?

This converter allows users to transform length values from petameters, an extremely large SI unit used primarily in astronomy, into US survey links, a smaller historical land surveying unit. It supports tasks requiring conversion between astronomical and legacy surveying measurements.

How to Use This Tool?

Input the length value in petameters into the converter field
Select petameter as the original unit and link (US survey) as the target unit
Click the convert button to get the equivalent length in links
Review the converted value displayed for your measurement needs

Key Features

Converts extremely large distances from petameters to US survey links effortlessly
Supports translation of scientific measurements to legacy land surveying units
Browser-based and easy to use without special software
Provides direct conversion using the exact established ratio

Examples

Convert 2 Pm: equals 9941919191919200 links
Convert 0.5 Pm: equals 2485479797979800 links

Common Use Cases

Expressing astronomical distances in older land survey units for cross-disciplinary research
Updating or interpreting historical US land survey plats and deeds measurements
Bridging scientific data with legacy cadastral and land management records

Tips & Best Practices

Always verify the context to ensure using appropriate units for your task
Understand that petameters suit very large astronomical scales while links serve smaller, historical land measurement roles
Use this tool mainly for specialized interdisciplinary conversions involving astronomy and surveying

Limitations

Conversion is generally theoretical due to vastly different measurement scales
Variation in precision may arise from historical definitions of US survey feet
Petameter is rarely used outside astronomy and the link is mostly obsolete except in legacy contexts

Key Terminology

Petameter (Pm): An SI unit of length equal to 10^15 metres, used for very large-scale astronomical distances.
Link (US survey) [li]: A historical unit of length equal to 1/100 of a Gunter's chain, approximately 0.201168 meters, used in US land surveying.
Gunter's Chain: A measuring chain of 66 US survey feet traditionally used in land surveying, subdivided into 100 links.
