To convert square centimeters to circular mils, multiply the value by 197,353. To go the other way, multiply circular mils by 5.06707 × 10⁻⁶ to get square centimeters.
| Square Centimeters (cm²) | Circular Mils (cmil) |
|---|---|
| 1 cm² | 197,353 cmil |
| 2 cm² | 394,705 cmil |
| 5 cm² | 986,763 cmil |
| 10 cm² | 1,973,530 cmil |
| 20 cm² | 3,947,050 cmil |
| 50 cm² | 9,867,630 cmil |
| 100 cm² | 19,735,300 cmil |
| 500 cm² | 98,676,300 cmil |
| 1,000 cm² | 197,353,000 cmil |
250 cm² × 197,353 = 49,338,100 cmil
Try this example →Square centimeter (cm²). A square centimeter is the area of a square with 1 cm sides, widely used in schools and for small surfaces.
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.
There are 197,353 circular mils in one square centimeter.
Multiply the number of square centimeters by 197,353. For example, 10 square centimeters equal 1,973,530 circular mils.
One circular mil equals 5.06707 × 10⁻⁶ square centimeters.
