What is a petameter used for?

A petameter is an SI unit of length used for measuring extremely large distances such as nearby stars and certain interstellar structures.

Where was the link unit historically used?

The link was historically used in English land surveying, particularly in the 18th and 19th centuries for property boundaries and cadastral records.

Why convert petameters to links?

Converting petameters to links helps relate astronomical distances to historical land measurement units, assisting in legal and historical research with old maps and property data.

What Is This Tool?

This converter translates length values from petameters (Pm), an SI unit used for very large astronomical distances, into links (li), a historic English unit once used in land surveying. It bridges modern scientific measurement with traditional surveying units.

How to Use This Tool?

Enter the value in petameters (Pm) you want to convert.
Select petameter as the input unit and link as the output unit.
Click the convert button to see the equivalent length in links (li).

Key Features

Converts petameters to links accurately based on established conversion rates.
Simplifies understanding of astronomical scales in terms of historical land measurement units.
Browser-based and easy to use with quick input and conversion steps.

Examples

2 Pm converts to 9,941,939,075,797,400 li.
0.5 Pm converts to 2,485,484,768,949,350 li.

Common Use Cases

Expressing extremely large astronomical distances in land surveying units.
Analyzing historical cadastral records alongside modern measurements.
Comparing astronomical scales with old property boundary measurements.

Tips & Best Practices

Ensure the value entered is appropriate for large-scale distance measurements due to the vastly different unit sizes.
Use this converter primarily for bridging modern astronomical data with historical surveying records.
Be mindful of the very large numeric results when converting petameters to links.

Limitations

Petameter units represent extremely large distances making converted values into links impractically large.
The link is an obsolete unit with limited use outside historical land measurement.
Conversion accuracy may vary when applying astronomical distances to units designed for small-scale surveying.

Key Terminology

Petameter (Pm): An SI unit of length equal to 10^15 metres, used for extremely large astronomical distances.
Link (li): A historic English unit of length used in surveying, equal to 1/100 of Gunter's chain or approximately 0.201168 metres.
Gunter's chain: A historic measuring device used in English land surveying, where one link equals 1/100 of the chain.
