To convert circular mils to square kilometers, multiply the value by 5.06707 × 10⁻¹⁶. To go the other way, multiply square kilometers by 1.97353 × 10¹⁵ to get circular mils.
| Circular Mils (cmil) | Square Kilometers (km²) |
|---|---|
| 1 cmil | 5.06707 × 10⁻¹⁶ km² |
| 2 cmil | 1.01341 × 10⁻¹⁵ km² |
| 5 cmil | 2.53354 × 10⁻¹⁵ km² |
| 10 cmil | 5.06707 × 10⁻¹⁵ km² |
| 20 cmil | 1.01341 × 10⁻¹⁴ km² |
| 50 cmil | 2.53354 × 10⁻¹⁴ km² |
| 100 cmil | 5.06707 × 10⁻¹⁴ km² |
| 500 cmil | 2.53354 × 10⁻¹³ km² |
| 1,000 cmil | 5.06707 × 10⁻¹³ km² |
25 cmil × 5.06707 × 10⁻¹⁶ = 1.26677 × 10⁻¹⁴ km²
Try this example →250 cmil × 5.06707 × 10⁻¹⁶ = 1.26677 × 10⁻¹³ km²
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 kilometer (km²). A square kilometer is one million square meters (100 hectares), used for countries, cities and lakes.
There are 5.06707 × 10⁻¹⁶ square kilometers in one circular mil.
Multiply the number of circular mils by 5.06707 × 10⁻¹⁶. For example, 10 circular mils equal 5.06707 × 10⁻¹⁵ square kilometers.
One square kilometer equals 1.97353 × 10¹⁵ circular mils.
