How to Use SWG to KG Calculator
Follow these simple steps to use the swg to kg calculator effectively:
- Select the SWG (Standard Wire Gauge) number from the dropdown list.
- Enter the length of the wire and choose the unit (meters or feet).
- Choose the material type (Copper, Aluminum, or Steel) to apply the correct density.
- Click the "Calculate Weight" button.
- View the result in kilograms (kg) displayed instantly.
Pro Tips:
- Always double-check units before calculation.
- Use correct material density for accurate results.
- Longer wire length increases total weight significantly.
Conversion / Calculation Guide
How to Convert SWG to KG
You cannot convert SWG directly to kg without knowing the wire length and material material. To find the weight, you must calculate the volume of the wire and then multiply it by the density of the material.
The Formula:Where:
- Volume = π × (d / 2)² × Length
- d = wire diameter in meters
- Length = total wire length in meters
- Density = dependent on the material (e.g., Copper ≈ 8960 kg/m³)
Step-by-step Example
Example: Calculate the weight of 10 meters of 10 SWG copper wire.
1. Find diameter of 10 SWG: Diameter ≈ 3.251 mm = 0.003251 m
2. Calculate cross-sectional area: Area = π × (0.003251 / 2)² ≈ 8.30 × 10⁻⁶ m²
3. Calculate volume: Volume = Area × 10m = 8.30 × 10⁻⁵ m³
4. Apply density for Copper (8960): Weight = 8.30 × 10⁻⁵ × 8960 ≈ 0.743 kg

FAQs – SWG to KG Calculator
It is a specialized tool that converts standard wire gauge (SWG) into total weight (kg) based on the wire's length and the material's specific density.
No. SWG only defines the diameter. To find weight, you must also provide the wire length and the material type (like copper or aluminum) to determine density.
Different materials have different densities. For example, copper (8960 kg/m³) is much heavier than aluminum (2700 kg/m³), so a copper wire will weigh more than an aluminum wire of the same gauge and length.
The chart provides approximate reference values for copper. For precise engineering or industrial planning, always use the calculator which accounts for exact dimensions and material constants.
These calculations are vital in electrical wiring, construction material estimating, telecommunications manufacturing, and general metal fabrication industries.
Meters are the standard for scientific calculations. Our calculator supports both meters and feet for your convenience, performing internal conversions automatically.
Yes. As SWG numbers decrease, the wire diameter increases. A larger diameter means more volume per meter, which directly results in higher weight.
