Wire Calculators & Gauge Tools
Professional wire calculation tools � wire weight, ring weight, SWG ? AWG ? mm conversion and reference tables. Built for buyers, engineers and makers.
Calculate the weight of a wire coil or straight length. Useful for estimating material cost, freight weight and stock requirements.
Weight = p � (d/2)� � Length � Density
Where d = diameter in cm, Length in cm, Density in g/cm�. Result in grams, converted to kg.
| Copper (ETP) | 8.89 g/cm� |
| Aluminium (EC) | 2.70 g/cm� |
| GI / Mild Steel | 7.85 g/cm� |
| SS 304 | 7.93 g/cm� |
| SS 316 | 7.99 g/cm� |
Once you have your weight estimate, request a quote with that quantity.

Wire circumference per ring = p � (Inner Diameter + Wire Diameter)
Volume per ring = p � (Wire Diameter / 2)� � Wire Circumference
Weight per ring = Volume � Density
Note: This is the mean-diameter formula (standard for jump ring calculations). Actual weight may vary �2% due to cut waste and material tolerances.
AR = Inner Diameter � Wire Diameter. Typical chainmaille AR: 3.5�6.0. Industrial rings: 3�15.
We make rings to your spec � material, gauge, ID, quantity. Open or closed.

* Weights calculated using standard densities: Copper 8.89 g/cm�, Aluminium 2.70 g/cm�, GI/Steel 7.85 g/cm�. Actual values may vary slightly by temper and alloy. All data for guidance only.
Wire Specification Reference Guide
Everything buyers, engineers and makers need to specify wire correctly the first time.
SWG (Standard Wire Gauge) is the system used in India and the UK � IS and BS standards reference SWG numbers. AWG is the American standard used in ASTM, UL and NEC specifications. When sourcing wire internationally or reading foreign datasheets, always confirm which gauge system applies before ordering.
Accurate weight estimation is essential for freight planning, cost estimation and inventory management. Use our Wire Weight Calculator to determine coil weight before requesting a quote � we can then confirm pricing per kg or per coil for your specific gauge and material.
Aspect Ratio (AR) = Inner Diameter � Wire Diameter. For chainmaille, AR determines which weaves are achievable. Box chain: AR ~3.0�3.5. Full Persian: AR ~3.7�4.2. For industrial filter rings, higher AR gives larger flow aperture per ring. Our ring calculator outputs AR automatically.
