Share:

GAUGE SWG DIAMETER (Inches) AWG DIAMETER (Millimeters)
14 Gauge Wire 0.0800 in 1.626 mm
16 Gauge Wire 0.0640 in 1.290 mm

How do you calculate the thickness of a cable?

This is the cable’s radius, measured in meters. Multiply your answer by 39.37 to convert it to inches: 0.006415 x 39.37 = 0.2526. Multiply the answer by 2: 0.2526 x 2 = 0.5052 inches. This is the cable’s necessary thickness.

How can I tell what gauge my amp is?

To determine what gauge wire you need, consider the carrying capacity and the amount of current the wire needs to conduct (measured in amperage or amps). Wire gauge is directly related to how many amps you need to run through it. The distance you need the wire to go can also impact the gauge of wire you need.

### How many amps can a 10mm cable carry?

A 10mm cable can carry between 40 and 70 amps of current.

### Is 16 AWG better than 18AWG?

The 16 AWG wire can accommodate an appliance with a higher wattage (power) than an 18 AWG wire. 16AWG has less power loss, so is better for speaker wires or extension cords, unless the load is small and the wire needs to be hidden.
