Frequently Asked Questions
-
What is a square mil used for?
-
A square mil specifies very small planar areas such as PCB copper traces and thin electrical conductors in imperial units.
-
Why convert square mil to square chain?
-
This conversion helps translate very small industrial measurements into larger land measurement units traditionally used in surveying and property documentation.
-
Is square chain commonly used today?
-
No, the square chain is primarily a historical imperial unit and is less common in modern land measurements, which favor acres or hectares.
Key Terminology
-
Square Mil [mil^2]
-
An area unit representing a square with sides of one mil (0.001 inch), used for very small surface areas in electronics and manufacturing.
-
Square Chain [ch^2]
-
An imperial area unit equal to the area of a square with sides one chain (66 feet), commonly used historically for land measurement.
-
Conversion Rate
-
The exact factor used to convert square mil to square chain: 1 square mil equals approximately 1.5942250790736e-12 square chain.
