What is SWG to mm Conversion? Full Guide with Tool & Chart
Introduction – SWG & mm in Wire Sizing
SWG (Standard Wire Gauge) is a British wire sizing system mainly used in electrical and mechanical engineering. It is a number-based system – eg 0 SWG, 1 SWG, 2 SWG, 3 SWG, 4 SWG, 5 SWG, 6 SWG, 7 SWG, 8 SWG, 9 SWG, 10 SWG, 11 SWG, 12 SWG, 13 SWG, 14 SWG, 15 SWG, 16 SWG, 16.5 SWG, 17 SWG, 17.5 SWG, 18 SWG, 18.5 SWG, 19 SWG, 19,.5 SWG, 20 SWG, 20.5 SWG, 21 SWG, 21.5 SWG, 22 SWG, 22.5 SWG, 23 SWG, 23.5 SWG, 24 SWG, 25 SWG, 26 SWG, 27 SWG, 28 SWG, 29 SWG, 30 SWG, 31 SWG, 32 SWG, 33 SWG, 34 SWG, 35 SWG, 36 SWG, 37 SWG, …… 45 SWG, etc.
Each number corresponds to a specific diameter (mm).
Example:
- 10 SWG = 3.25 mm
- 24 SWG = 0.559 mm
On the other hand, mm (millimeter) is the international unit that represents the physical thickness of each wire.
SWG to mm Conversion Tool – How It Works?
Your “Wire Gauge Checker Tool” is an interactive converter in which the user can:
- SWG value is given → tool diameter is given in mm
- or mm value is entered → the tool shows the nearest matching SWG
Use-cases:
If an electrician has 1.6 mm wire, what will be its SWG number? This tool will help you find out easily.

Where is SWG to mm Used?
Common Applications:
- 🌀 Motor Winding
- 💡 Electrical Wiring
- 🔌 Transformer Coils
- 🧪 Lab Equipment
- 🔍 Precision Electronics
- 🛠️ DIY Projects
How is SWG Measured?
The Swag scale is non-linear. As the Swag number increases, the diameter of the wire decreases. This scale is based on the diameter of historical tools.
Formulaic Conversion:
It does not convert by a fixed formula. Each value has a fixed mapping, which can be derived from the chart itself.
People Also Ask
Q1: What is 18 SWG in mm?
A: 1.219 mm (approx)
Q2: How to convert mm to SWG manually?
A: Manual conversion is tough. Use chart or online tool.
Q3: Which is thicker – 10 SWG or 20 SWG?
A: 10 SWG is thicker. As SWG number increases, wire gets thinner.
Q4: Is AWG same as SWG?
A: No, AWG (American Wire Gauge) is different from SWG, UK, India, Commonwealth countries Don’t confuse both.
