An arpent is a historical French unit of length used mainly for land measurement, especially in colonial Quebec and Louisiana.

What does mil or thou measure?

A mil, also called a thou, is one thousandth of an inch, commonly used in manufacturing and engineering for small thicknesses and tolerances.

Why convert arpent to mil?

Users convert arpent to mil to interpret historic land dimensions into fine precision units useful in modern legal, surveying, or fabrication contexts.

How to Convert from Arpent to Mil [mil, thou]

What Is This Tool?

This converter allows you to translate lengths measured in arpents, a historical French unit, into mils (also known as thous), a very small unit commonly used in U.S. manufacturing and engineering for precise measurements.

How to Use This Tool?

Input the length value in arpents.
Select the source unit as arpent and the target unit as mil.
Click the convert button to see the equivalent length in mils.
Use the result for detailed engineering, legal, or fabrication needs.

Key Features

Converts arpent units, historically used in French land measurement, into mils (thous).
Supports detailed length conversions for applications requiring fine precision.
Browser-based and easy to use for translating historic cadastral data.
Provides clear results per the exact conversion ratio given.

Examples

2 arpents equals 4,608,000 mils.
0.5 arpent equals 1,152,000 mils.

Common Use Cases

Converting historical land measurements from French colonial surveys.
Interpreting old property descriptions for legal or surveying purposes.
Specifying thicknesses, clearances, or tolerances in manufacturing and electronics using very small units.
Analyzing parcel dimensions on cadastral maps with modern precision.

Tips & Best Practices

Verify the specific historical context of the arpent value due to regional and temporal differences.
Use the conversion primarily for data processing rather than direct practical measurement.
Double-check conversions when applying to sensitive legal or engineering tasks.
Understand that mil is a measurement used for very small lengths, appropriate in specialized fields.

Limitations

The arpent varied by location and era, so the conversion may not be exact without context.
The mil unit is extremely small compared to arpent, making direct comparison uncommon in everyday use.
