What is a point in measurement?

A point is a typographic unit of length used mainly to specify font sizes and spacing in printing and digital layouts.

What is a US survey chain?

The US survey chain is a traditional length unit equal to 66 US survey feet, historically used in U.S. land surveying and cadastral work.

When should I convert points to chains (US survey)?

Conversion is useful when interpreting or integrating typographic measurements with historical land surveying data and documents.

What Is This Tool?

This converter changes values from points, a unit used in typography for font sizes and layout spacing, into chains (US survey), a historic land measurement unit mostly used in U.S. surveying and cadastral work.

How to Use This Tool?

Enter the length value in points.
Select 'point' as the original unit and 'chain (US survey) [ch]' as the target unit.
Click convert to get the equivalent length in chains.
Use the result for historical land records or mapping projects.

Key Features

Converts typographic points to US survey chains accurately
Supports historical land surveying unit conversions
Useful for integrating print/layout measures with legacy survey data
Browser-based and easy to use for quick calculations

Examples

100 points is equal to 0.00175364 chains (US survey).
500 points converts to 0.0087682 chains (US survey).

Common Use Cases

Specifying font size and layout in digital and print typography.
Interpreting distances in historical U.S. land deeds and surveys.
Converting legacy survey measurements for modern GIS mapping.
Describing rural property boundaries and right-of-way dimensions.

Tips & Best Practices

Use this conversion mainly for specialized historical or cadastral analysis.
Remember that points are small units, so results in chains will be very tiny fractions.
Double-check context since typographic and surveying measurements differ in scale and purpose.

Limitations

Points are designed for small scale typography, not large scale land measurement.
Conversion values often produce very small fractions, limiting practical use.
Accuracy is constrained by differences in unit purposes and rounding effects.
