Quick Answer
AWG (American Wire Gauge) is a logarithmic scale where lower numbers = thicker wire. The formula d(mm) = 0.127 × 92^((36-AWG)/39) converts any gauge to diameter. Each 3 AWG steps doubles the cross-sectional area and halves the resistance.

Design Notes
AWG is used throughout North America while IEC metric sizes (mm²) are standard in Europe and Asia. There is no exact 1:1 mapping between the systems. For current-carrying capacity, always consult your local electrical code (NEC in the US, IEC 60364 internationally) as ampacity depends on installation conditions.
Common Mistakes
- 1
Thinking higher AWG = thicker wire. It is the OPPOSITE: AWG 10 is much thicker than AWG 24.
- 2
Using the same ampacity rating for wire in conduit vs free air — bundled wires must be derated significantly.
- 3
Ignoring voltage drop for long wire runs — even if the wire can handle the current, the voltage drop may be excessive.
Engineering Handbox
1. d(inches) = 0.005 × 92^((36-12)/39) = 0.0808 in 2. d(mm) = 0.127 × 92^0.615 = 2.053 mm 3. Area = π/4 × 2.053² = 3.31 mm² 4. Ampacity (NEC): 20A in 60°C insulation
Knowledge Base
Bedeutet höherer AWG-Wert dickeren Draht?
Nein, AWG ist invertiert. AWG 10 (2,59 mm) ist viel dicker als AWG 24 (0,51 mm).
Was ist die AWG-zu-mm Formel?
d(mm) = 0,127 × 92^((36-AWG)/39). Alle 3 AWG-Stufen verdoppelt sich der Querschnitt.
Welchen AWG-Draht für 15A?
AWG 14 minimum (NEC-Vorschrift USA). 20A: AWG 12. 30A: AWG 10. Längere Strecken erfordern größere Querschnitte.
Was ist das metrische Äquivalent?
AWG 10 ≈ 6mm², AWG 12 ≈ 4mm², AWG 14 ≈ 2,5mm², AWG 18 ≈ 1,0mm². IEC-Normquerschnitte in mm² weltweit außer Nordamerika.
Was ist der Unterschied fest und flexibel gleicher AWG?
Gleicher Querschnitt = gleicher Widerstand = gleiche Strombelastbarkeit. Flexibel ist biegsamer, fester Draht formstabil.
