Use this free online conversion calculator to swiftly and accurately convert:
- Mils to cmils
- Mils to inches (in)
- Mils to mm
The calculator is based on the following formulas:
- Converting Mils to Circular Mils (cmils) and Inches:
- 1 cmil = (length in mils)²
- 1 inch (in) = 1,000 mils
- Converting Mils to mm:
- (Length in mils) x 0.0254
Worked Example:
Suppose the diameter of a wire is 240 mils (0.24 inches). The area of the wire based on its diameter in circular mils is calculated as follows:
- Area = (diameter of the wire in mils)² = 240² = 57,600 cmils or 57.6 kcmils.
In summary:
- 240 mils = 0.24 inches = 57,600 cmils = 57.6 kcmils.

Formula for converting mils to circular mils (cmils), inches and mm
This mils calculator above is based on the following conversions:
- For mils to cmils, 1 cmil = (length in mils)² .
- 1 inch (in) = 1,000 mils
- For mils to inches, 1,000 mils = 1 inch
- For mils to mm, (length in mils) x 0.0254
Worked example
For example, if the diameter of a wire is 240 mils (0.24 inches), then the area of the wire based on its diameter in circular mils is (diameter of the wire in mils)² = 240² = 57,600 cmils or 57.6 kcmils.
i.e. 240 mils = 0.24 inches =57,600 cmils =57.6 kcmils
