SWG AWG Converter: How Chakan Factories Avoid Import Rejects

Chakan MIDC factories lose Rs 2L/week from SWG/AWG mixups with overseas suppliers. 70% of import rejections happen because drawings specify SWG but suppliers send AWG - critical size mismatch.

Why Factories Need Instant SWG ↔ AWG Conversion

SWG 16 = 1.63mm vs AWG 14 = 1.63mm (exact match)
SWG 18 = 1.22mm vs AWG 16 = 1.29mm (0.07mm difference!)
Import drawings = British SWG standard
US suppliers = American AWG standard

Common Gauge Conversion Problems + Solutions

0.91mm ordered: SWG 20 = AWG 19 (match)
0.71mm wrong: SWG 22 ≠ AWG 21 (check both!)
Area mismatch: Calculate mm² before ordering
Machine setup: Die size must match exact mm

Save Rs 8L/month - Convert ALL drawings to mm, verify with micrometer, match die sizes exactly!

❓ Frequently Asked Questions

Why SWG 16 ≠ AWG 16 exactly? +

SWG 16 = 1.63mm, AWG 16 = 1.29mm (0.34mm difference!). British SWG bigger than American AWG for same number.

What is most common Chakan factory mixup? +

SWG 18 (1.22mm) vs AWG 16 (1.29mm) = 0.07mm difference causes die breakage + production stoppage.

How to verify supplier wire gauge? +

Micrometer 3-point measurement at 90° intervals. Reject if ±0.02mm tolerance exceeded. Always measure mm, never trust gauge number!

Which standard for Indian import drawings? +

99% British SWG (IS 398 standard). US suppliers default AWG - specify "SWG REQUIRED" in PO clearly.

Why calculate cross-section area mm²? +

Current capacity based on mm², not gauge number. SWG/AWG only for ordering - mm² determines amp rating + machine settings.

DISCLAIMER: For procurement reference only. Always verify physical wire diameter with micrometer before production.
