What Is This Tool?

This converter allows users to transform area values expressed in square centimeters, a widely used SI-derived unit for small surface areas, into circular mils, a specialized unit used mainly in electrical engineering for round wire cross-sections.

How to Use This Tool?

  • Enter the area value you want to convert in square centimeters.
  • Select 'square centimeter [cm²]' as the input unit.
  • Choose 'circular mil' as the output unit.
  • Click the convert button to see the result.
  • Use the result to specify or check wire cross-sectional areas in electrical applications.

Key Features

  • Converts area from square centimeter (cm²) to circular mil accurately.
  • Supports translation between general surface area units and electrical conductor sizing standards.
  • Browser-based and easy to use with no installation needed.
  • Ideal for electrical engineers, procurement specialists, and technical documentation.

Examples

  • 2 cm² converts to 394,705.048278 circular mil.
  • 0.5 cm² converts to 98,676.2620695 circular mil.
  • Multiply the square centimeter value by approximately 197,352.524139 to get circular mil.

Common Use Cases

  • Converting PCB pad areas and small machine part surfaces to circular mil for wire sizing.
  • Determining cross-sectional area of electrical wires and cables according to American Wire Gauge (AWG).
  • Preparing engineering and procurement documents involving power distribution conductors.

Tips & Best Practices

  • Ensure you correctly identify the input unit as square centimeter before converting.
  • Use this conversion primarily for electrical wire cross-section calculations.
  • Avoid applying circular mil measurements to non-circular or general surface areas.
  • Double-check unit definitions to prevent conversion errors.

Limitations

  • Circular mil is a non-SI unit and applies mainly to electrical wire cross-sections.
  • Not suitable for measuring general surface areas outside electrical contexts.
  • Assumes the wire cross-section is circular; does not apply to other shapes.
  • Accuracy depends on proper understanding and use of units.

Frequently Asked Questions

What is a square centimeter used for?
A square centimeter measures small surface areas in scientific, engineering, and everyday contexts such as small components, microscope slides, and packaging.

Why convert square centimeters to circular mil?
Converting to circular mil allows electrical engineers to specify and size round conductors accurately using a unit common in the electrical industry.

Can this conversion be used for non-electrical areas?
No, circular mil is specific to electrical wire cross-sectional areas and is not appropriate for general surface area measurements.

Key Terminology

Square Centimeter (cm²)
An SI-derived unit of area equal to the area of a square with sides one centimeter long, used to quantify small surface areas.
Circular Mil
A non-SI unit of area representing the cross-sectional area of a circle with a diameter of one mil (0.001 inch), used mainly for round electrical wire conductors.
American Wire Gauge (AWG)
A standard used in North America to denote the diameter and cross-sectional area of electrical conductors.
