What Is This Tool?
This tool converts length values from points, a typographic measurement unit, to links (li), a historic English surveying unit. It assists users in interpreting old land records and cadastral documents by translating typographic lengths into historic land measurement units.
How to Use This Tool?
-
Enter the length value in points into the input field.
-
Select 'point' as the original unit and 'link [li]' as the target unit.
-
Initiate the conversion to get the equivalent length in links.
-
Use the converted value to interpret historical land measurement data or typographic dimensions.
Key Features
-
Converts point values to link (li) units based on a specific conversion rate.
-
Supports length measurement conversions related to typography and historical surveying.
-
Web-based and easy to use without installation.
-
Facilitates historical land surveying and cadastral research tasks.
Examples
-
12 Points equals 0.0210437712 Link [li] using the formula 12 × 0.0017536476.
-
72 Points equals 0.1262626272 Link [li] calculated with 72 × 0.0017536476.
Common Use Cases
-
Interpreting and converting lengths in old land deeds and cadastral documents.
-
Reconstructing historical property boundaries using traditional surveying units.
-
Typography analysis of old documents where points apply in conjunction with land measurement units.
-
Historical land surveying and archival map reconstruction.
Tips & Best Practices
-
Ensure you know which point definition applies (PostScript or TeX) for accurate context.
-
Use the conversion mainly for historical and research-related purposes.
-
Cross-reference converted measurements with original documents for verification.
-
Understand the difference in scale between typographic points and surveying links.
Limitations
-
Direct practical conversions between points and links are uncommon outside historical research.
-
Different point definitions (PostScript vs TeX) can slightly affect conversion precision.
-
The point is very small compared to the link unit, limiting everyday applicability.
-
Conversion is primarily useful for interpreting archaic land measurement records.
Frequently Asked Questions
-
What is a point in measurement terms?
-
A point is a typographic unit of length used to set font sizes, spacing, and layout in printing and digital typography, commonly defined as 1/72 inch.
-
What is a link (li) unit?
-
A link (li) is a historic English unit of length used in land surveying, equal to 1/100 of Gunter's chain or approximately 0.201168 meters.
-
Why would I convert from point to link?
-
Converting from point to link helps translate typographic length measurements into historic land surveying units, useful for interpreting old land records and cadastral data.
