Wire Weight Calculator
Estimate the weight of wire based on material, gauge or diameter, and length. Supports AWG/mm² and U.S./metric units.
Wire Weight Calculator – Your Go-To Guide for Accurate Wire Estimation
Working on an electrical project? Whether big or small, getting your materials right is crucial—and that includes knowing the exact weight of your wire. That’s where this Wire Weight Calculator comes in.
This simple yet powerful tool helps you calculate the weight of any wire based on its material, size, and length. Quick, accurate, and incredibly useful, it’s perfect for project planning, budgeting, and ensuring safe installation or transport without overloading.
Why Wire Weight Matters
Imagine ordering 1,000 feet of copper wire—that’s a heavy package! Knowing the weight helps you:
✔ Avoid Shipping Surprises – Prevent overweight fees and unexpected delivery costs.
✔ Plan Your Budget – Some suppliers price by weight, so estimate costs upfront.
✔ Check Structural Limits – Ensure ceilings, walls, or conduits can handle the load.
✔ Reduce Waste – Order the exact amount you need—no excess, no shortages.
How the Calculator Works
Just three simple steps:
1️⃣ Select the wire material – Copper, aluminum, or steel.
2️⃣ Enter the wire size – Use AWG (e.g., 12-gauge) or mm² (metric).
3️⃣ Input the length – In feet or meters.
Hit “Calculate”, and you’ll instantly get the weight in kilograms, pounds, and grams.
Behind the scenes, the tool uses standard material densities and volume calculations—no complex math required!
Wire Material Densities (Reference)
Material | Density (g/cm³) |
---|---|
Copper | 8.96 |
Aluminum | 2.70 |
Steel | 7.85 |
These values ensure accurate weight estimates based on wire size and length.
Quick Example
Let’s say you have:
- Material: Aluminum
- Size: 6 AWG
- Length: 250 feet
Plug in the numbers, and the calculator gives you the total weight in seconds—no manual calculations needed!
FAQs – Clear Answers to Common Questions
Q: Does this work only for copper wire?
No! It supports copper, aluminum, and steel—more materials may be added soon.
Q: What’s the difference between AWG and mm²?
- AWG (American Wire Gauge) is common in the U.S.—smaller numbers = thicker wire.
- mm² (square millimeters) is metric—larger numbers = more cross-sectional area.
Q: Is this accurate enough for professional use?
Yes! It uses standard engineering values, making it reliable for real-world projects.
Q: Can I use it for stranded wire?
Absolutely—just enter the labeled size (AWG or mm²), and it works the same way.
