Metric AWG to MM2 Conversion Chart
In Europe, the cross-sections of electrical conductors are based on the IEC 60228 standard (UNE EN 60228), but it is not the only global reference. In the United States and many other American countries, the standard system used to measure the diameter of cables and wires is the American Wire Gauge (AWG). This unit is based on the American standards ASTM B 496 and ASTM B 400.
If you work in a sector involving the measurement of cables or wires, you may have come across the terms AWG and mm2. Both units of measurement are used to indicate the thickness or diameter of cables and wires, but they are not interchangeable. To convert between these two units, you will need a conversion table.
The higher the AWG number, the thinner the cable. For example, a 16 AWG cable is thicker than a 22 AWG cable. On the other hand, mm2 stands for square millimeters and is used as a standard unit of measurement for the diameter of cables and wires in most parts of the world that use the metric decimal system.
A thin cable has higher resistance to the flow of current due to its smaller cross-sectional area. Conversely, a thicker cable has lower resistance and can efficiently carry higher currents.
To check the AWG to mm2 equivalence, you’ll need to refer to a conversion table. These tables usually list AWG sizes in one column and their corresponding mm2 measurements in another column. You can use these tables to find the equivalent between the two units for any given size.
Electric Cable Conversion Table from AWG to mm2
Here is the conversion table:
| AWG/kcmil | MM2 |
|---|---|
| #22 | 0.50 |
| #20 | 0.75 |
| #18 | 1 |
| #16 | 1.5 |
| #14 | 2.5 |
| #12 | 4 |
| #10 | 6 |
| #8 | 10 |
| #6 | 16 |
| #4 | 25 |
| #2 | 35 |
| #1 | 50 |
| #2/0 | 70 |
| #3/0 | 95 |
| #4/0 | 120 |
| 250 kcmil | 150 |
| 350 kcmil | 185 |
| 450 kcmil | 240 |
| 550 kcmil | 300 |
| 750 kcmil | 400 |
When looking for the maximum permissible currents for each cable according to AWG, it is important to highlight that the UNE-HD 60364-5-52 standard specifies the formula for calculating permissible currents. For this calculation, it is important to have certain information such as the conductor cross-section in mm², the installation system, the conductor material (copper or aluminum), and the type of insulation, whether it is thermoplastic (PVC type) or thermosetting (XLPE type).
In conclusion, if you need to convert between AWG and mm2, a conversion table is an essential tool. With this table, you can quickly convert between these two units of measurement and ensure that you are using the correct cable for your application.
