To convert circular mils to square centimeters, multiply the value by 5.06707 × 10⁻⁶. To go the other way, multiply square centimeters by 197,353 to get circular mils.
| Circular Mils (cmil) | Square Centimeters (cm²) |
|---|---|
| 1 cmil | 5.06707 × 10⁻⁶ cm² |
| 2 cmil | 1.01341 × 10⁻⁵ cm² |
| 5 cmil | 2.53354 × 10⁻⁵ cm² |
| 10 cmil | 5.06707 × 10⁻⁵ cm² |
| 20 cmil | 0.000101341 cm² |
| 50 cmil | 0.000253354 cm² |
| 100 cmil | 0.000506707 cm² |
| 500 cmil | 0.00253354 cm² |
| 1,000 cmil | 0.00506707 cm² |
25 cmil × 5.06707 × 10⁻⁶ = 0.000126677 cm²
Try this example →250 cmil × 5.06707 × 10⁻⁶ = 0.00126677 cm²
Try this example →Circular mil (cmil). A circular mil is the area of a circle 0.001 inch across, the standard measure of wire cross-section in American Wire Gauge.
Square centimeter (cm²). A square centimeter is the area of a square with 1 cm sides, widely used in schools and for small surfaces.
There are 5.06707 × 10⁻⁶ square centimeters in one circular mil.
Multiply the number of circular mils by 5.06707 × 10⁻⁶. For example, 10 circular mils equal 5.06707 × 10⁻⁵ square centimeters.
One square centimeter equals 197,353 circular mils.
