Question 1

How do you convert AWG to mm²?

Accepted Answer

10 AWG = 5.26 mm², 12 AWG = 3.31 mm², 14 AWG = 2.08 mm². Metric uses cross-sectional area.

Question 2

Why does Europe use mm² for wire?

Accepted Answer

Metric countries use cross-sectional area (mm²) which directly relates to current capacity. AWG is US-specific.

Question 3

What's the relationship between volts, amps, and watts?

Accepted Answer

Power (Watts) = Voltage (Volts) × Current (Amps). To find any value, divide or multiply: Amps = Watts/Volts, Volts = Watts/Amps.

Question 4

Is AWG or metric wire gauge better?

Accepted Answer

AWG (American Wire Gauge) uses arbitrary numbers where smaller = thicker. Metric (mm²) directly indicates cross-sectional area, making calculations easier.
