A foot of standard 12 AWG solid copper wire weighs about 0.0198 lbs (3.17 oz), while a 4/0 AWG wire weighs approximately 0.83 lbs
What does 2 copper wire weigh per foot?
AWG 2/0 (2-0) copper wire weighs about 0.4028 lbs per foot
This beefy size shows up in main service panels and big appliances. Thicker gauges pack on more weight because they cram more copper into the cross-section. Don’t just eyeball the insulation jacket—check the gauge marking to be sure.
How much does copper wire weigh?
Copper wire weight varies by gauge; for example, 12 AWG weighs 19.8 lbs per 1,000 feet and 14 AWG weighs 12.4 lbs per 1,000 feet
Use these numbers when you’re buying bulk or hauling scrap to the yard. Stranded wire can tip the scales a little differently thanks to the air gaps between strands. According to the Air-Conditioning, Heating, and Refrigeration Institute, copper weight tables stay consistent across manufacturers so you always know what you’re getting.

What does 350 copper wire weigh per foot?
350 kcmil copper wire weighs approximately 1.165 lbs per foot
You’ll spot this beast in industrial and commercial jobs where circuits need serious current. The insulation type—THHN, XHHW, whatever—doesn’t change the copper weight, though it might add a tiny bit to the total. Scrap yards usually lump 350 kcmil into the “bare bright” or “#1 copper” pile. For more details on pricing, see how much equity can I release.
How much does a foot of 500 copper weight?
A foot of 500 kcmil solid copper wire weighs about 1.544 lbs
Electricians love this size for subpanels and big motors. When you’re prepping wire for scrap, make sure the copper gleams—clean and shiny wire brings top dollar. The National Electrical Manufacturers Association (NEMA) sets the standards for 500 kcmil conductors so everything fits right.

What does 4 0 copper weigh per foot?
4/0 AWG copper wire weighs approximately 0.83 lbs per foot
This isn’t your everyday household wire. You’ll find it in welding cable and service entrances. That “0” in 4/0 means it’s way bigger than 4 AWG. If you’re unsure, grab a pair of calipers—some compact-stranded cables can look smaller than they really are. For more information on travel-related expenses, check out how much is SENTRI pass.
Should I strip my copper wire?
Yes—stripping bare bright copper wire maximizes your payout at scrap yards
Tossing insulated wire straight into the scrap bin leaves money on the table. Stripping peels off non-metallic coatings, dirt, and plastic that drag down purity and value. Grab a wire stripper sized for the gauge you’re working with so you don’t nick the copper inside. According to ISRI, clean, stripped copper #1 scrap can fetch anywhere from $0.10 to $0.30 more per pound than insulated wire.

How do you calculate the weight of copper in a wire?
Multiply the cross-sectional area (in mm²) by 8.96 to get kg/km, or by 0.00695 to get lbs/1000 ft
Say you’ve got a 2.5 mm² cable—just multiply by 8.96 and you get 22.4 kg/km. This math assumes pure copper density, so always double-check the actual size printed on the jacket. Nominal sizes can drift a little from one maker to the next. The ASTM keeps standard conductor sizing tables handy if you need them.
What is the weight of 600 MCM copper wire?
A foot of 600 kcmil copper wire weighs about 1.4 lbs
This monster shows up in high-current feeders and utility tie-ins. The insulation rating—THHN, RHW, etc.—affects the whole cable’s weight, but the copper core stays the same. If the wire’s uninsulated, scrap yards usually sort 600 kcmil as “bare bright.” For fantasy sports enthusiasts, you might enjoy reading about when can you pick up players in fantasy football.
How much is bare bright copper?
As of mid-2026, bare bright copper scrap is trading around $3.75 to $4.10 per pound
That price dances around every day based on market demand and LME copper futures. Sellers who want top dollar need to scrub their wire until it gleams and keep it far away from coated or alloyed copper. The London Metal Exchange posts daily settlement prices that most scrap yards use.
How much does a 14 2 Romex roll weigh?
A 250-ft roll of 14/2 NM-B Romex weighs approximately 15 pounds
The paper separator and outer PVC jacket both add to the total. Romex isn’t pure copper, so the plastic sheath keeps the weight lower than you might expect. Always peek at the roll label—those 500-ft reels tip the scales at about 30 lbs. Southwire, one of the biggest U.S. makers, lists these weights in their product datasheets. If you're interested in sports careers, you might want to know what subjects are needed to become a footballer.
What does 500 Kcmil THHN weigh?
A 500 kcmil THHN copper wire weighs about 826.7 lbs per 1,000 feet
THHN is a thermoplastic-insulated wire rated for 90°C in dry spots. The plastic jacket tacks on roughly 1–2% extra weight. When you’re figuring conduit fill, use the insulated diameter—0.814 in for 500 kcmil THHN. The NECA publishes raceway fill tables that electricians swear by.
How many amps can 4 0 Wire carry?
4/0 AWG copper wire can safely carry up to 310 amps at 60°C in free air or 260 amps in a raceway
Those numbers come straight from the 2026 National Electrical Code (NEC Table 310.16). Real-world capacity shifts with temperature, how full the conduit is, and how hot the terminations run. Size your overcurrent protection based on the wire’s ampacity, not the device’s rating.

How much does 4 0 Wire cost?
As of June 2026, 4/0 AWG copper welding cable costs $7.80 to $9.20 per linear foot depending on insulation and vendor
Prices swing with brand, stranding, and insulation—EPDM vs. PVC makes a difference. Buy 500 ft or more and you’ll often shave a few bucks off the unit price. Check local suppliers like Wesco or Graybar for current stock and delivery options.
What is the resistance of 1 000 feet of No 14 copper wire?
1,000 feet of 14 AWG solid copper wire has a DC resistance of 2.52 ohms at 20°C
That resistance number matters a lot when you’re running long cable runs and need to keep voltage drop in check. Heat changes things—every 10°C jump bumps resistance up by about 4%. For spot-on values at different temperatures, the NIST copper wire tables are the gold standard.
