AWG vs mm²: Cable Sizing Conversion for Product Records
AWG vs mm2 compared for cable sizing, conversion pitfalls, and enrichment of electrical product records.
Cable records often mix AWG, mm², conductor count, voltage rating, and jacket designation in one dense title. Buyers may search in either North American or metric terms, while supplier feeds often provide only one. Claro turns those strings into structured cable attributes: original value, normalized AWG, normalized mm², conductor count, jacket, voltage, and source provenance.
At a glance
| Dimension | AWG | mm² |
|---|---|---|
| Meaning | American Wire Gauge size | Conductor cross-sectional area in square millimeters |
| Number direction | Smaller AWG number means larger conductor | Larger mm² value means larger conductor |
| Common market | North American wire, cable, and electrical components | IEC-style cables and global industrial catalogs |
| Catalog risk | Sorted incorrectly as plain numbers | Rounded too aggressively from AWG conversion |
| Best practice | Keep original AWG and add normalized conversion | Keep original mm² and add normalized conversion |
Common enrichment problems
| Problem | Better product-record handling |
|---|---|
| AWG values sorted as text, so 10 AWG appears after 2 AWG | Store gauge as a typed numeric attribute with gauge-system metadata |
| Converted mm² values overwrite the original AWG | Keep original and converted fields separate |
| Conductor count merged with size, such as 3G1.5 or 18/3 | Parse conductor count, ground indicator, and conductor size into separate attributes |
| Cable family designation ignored | Decode designations such as H05VV-F or H07RN-F into jacket and voltage context |
| No source for converted value | Attach the source datasheet and mark conversion method or confidence |
Where Claro helps
Claro can read supplier titles, PDFs, and cable tables, identify the conductor-size notation, normalize it for search, and preserve the original value for auditability. That lets buyers find products using either AWG or mm² language without the catalog pretending the two systems are identical.

FAQ
What is the difference between AWG and mm²?
AWG is a North American wire gauge system where smaller numbers mean larger conductors. mm² states the conductor cross-sectional area directly in square millimeters, which is common in IEC-style cable data.
Can AWG be converted exactly to mm²?
AWG can be converted mathematically to an approximate cross-sectional area, but catalogs should preserve the original stated size and store any converted value as normalized or derived. Rounding and standard-size conventions matter.
Which fields should cable records include?
Store original conductor size, normalized AWG, normalized mm², conductor count, material, insulation, voltage rating, temperature rating, standard, and the source document used for the value.
