How this AWG to mm² converter works
AWG (American Wire Gauge) is the standard wire sizing system in North America. This converter uses the exact formula to calculate diameter and cross-sectional area in metric units.
Common AWG to mm² values
AWG 18=0.82mm², AWG 16=1.31mm², AWG 14=2.08mm², AWG 12=3.31mm², AWG 10=5.26mm², AWG 8=8.37mm², AWG 6=13.3mm², AWG 4=21.2mm², AWG 2=33.6mm², AWG 1/0=53.5mm², AWG 4/0=107mm².
FAQ
How do I convert AWG to mm²?
d(mm) = 0.127 × 92^((36-AWG)/39), then A = π×(d/2)². Every 3 AWG decrease ≈ doubles the area.
What does /0 mean in AWG?
1/0=AWG 0 (53.5mm²), 2/0=AWG 00, 3/0=AWG 000, 4/0=AWG 0000. Larger sizes use kcmil.
Is AWG 12 equal to 2.5mm²?
No, AWG 12 = 3.31mm². Chinese 2.5mm² ≈ AWG 14. Use exact values for critical applications.
