What Is This Tool?

This converter transforms area values from sections—a traditional land measurement unit in the U.S.—into square mils, a tiny imperial-derived area unit commonly used in precision manufacturing and electronics.

How to Use This Tool?

  • Enter the area value in sections you want to convert.
  • Select 'section' as the input unit and 'square mil [mil^2]' as the output unit.
  • Click the convert button to get the corresponding area in square mils.

Key Features

  • Converts large land parcel areas from sections to extremely small square mil units.
  • Supports precise unit translation bridging surveying and electronic engineering fields.
  • Browser-based and easy to use without any specialized software.

Examples

  • 1 Section equals 4,014,489,600,000,000 square mils.
  • 0.5 Section equals 2,007,244,800,000,000 square mils.

Common Use Cases

  • Describing rural property boundaries and legal land descriptions in the U.S.
  • Calculating planar area of PCB copper traces in electronics using imperial units.
  • Measuring cross-sectional areas of rectangular conductors in electrical engineering.

Tips & Best Practices

  • Understand the scale difference: sections are very large while square mils are extremely small.
  • Use this conversion mainly to translate large land areas into fine units for precision industries.
  • Avoid confusing square mils with circular mils as they represent different area measurements.

Limitations

  • Conversion is mostly theoretical due to huge scale differences between the units.
  • Square mil units are impractical for general land measurement purposes.
  • Must not confuse square mil with circular mil units, which have distinct definitions.

Frequently Asked Questions

What is a section in area measurement?
A section is a U.S. land measurement unit equal to one square mile or 640 acres, used for describing rural property and mapping.

What is a square mil [mil^2] used for?
Square mil is an imperial unit representing an extremely small area, mostly used in electronics and precision manufacturing.

Why convert from section to square mil?
To express large land parcel areas in very fine units relevant in fields like microfabrication and electronics.

Key Terminology

Section
A U.S. land unit equal to one square mile, used for legal land descriptions and cadastral surveying.
Square mil [mil^2]
An extremely small imperial-derived unit of area, representing the area of a square with 1 mil (0.001 inch) sides.
Circular mil
A unit of area measuring the cross section of a circle 1 mil in diameter, distinct from the square mil.
