How to convert AWG to mm

When calclating AWG from diameter or cross sectional area, the diameter and cross sectional area are rounded to the nearest AWG equivalent values.

Wire diameter calculation

The n gauge wire diameter d _n in millimeters (mm) is equal to 0.127mm times 92 raised to the power of 36 minus gauge number n, divided by 39:

0.127mm is the diameter of gauge #36.

Wire cross sectional area calculation

The n gauge wire’s cross sercional area A _n in square millimeters (mm 2 ) is equal to pi divided by 4 times the square wire diameter d in millimeters (mm):

Question: What Is 18 Awg Wire Used For

18-gauge are used for low-voltage lighting and lamp cords in 10 amps. 16-gauge are used for light-duty extension cords supporting 13 amps. 14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps.

What does 18 AWG wire mean?

AWG stands for American Wire Gauge. It pertains to the diameter of the wire. The lower the AWG, the more current capacity it can carry. For instance, a 16AWG is thicker and can carry 13 Amps, but an 18 AWG is thinner and can only carry 10 Amps.

How many amps can 18 AWG handle?

A conservative estimate for several feet of 18 AWG (American Wire Gauge) wire is 16 Amps. However, length plays an important role in the amount of Amps a wire can carry. If you have only 12 inches of wire, the 18 gauge wire can handle more than 16 Amps.

What can 18 gauge wire be used for?

When choosing the ideal electrical wire size for your project, use the following assigned Wire Use-Rated Ampacity: 18-gauge is suitable for lamp cords in 10 amps and other low-voltage lighting fixtures. 14-gauge is used for lamps, light fixtures, and lighting circuits with 15 amps.

Can I use 18 gauge wire for outlets?

No. The circuit breaker or fuse determines the minimun wire size that must be used. So for a 15 amp circuit the minimum wire gauge is 14 AWG. For a 20 amp circuit the minimum wire gauge is 12 AWG.

Is higher AWG better?

In general, a lower AWG number is better than higher AWG. AWG is of primary importance for wires that will carry electrical power — for example, home or business electrical wiring, extension cords or high-power wire in automotive or audio use.

What size wire is 18 AWG?

Share: GAUGE SWG DIAMETER (Inches) AWG DIAMETER (Millimeters) 12 Gauge Wire 0.1040 in 2.052 mm 14 Gauge Wire 0.0800 in 1.626 mm 16 Gauge Wire 0.0640 in 1.290 mm 18 Gauge Wire 0.0480 in 1.024 mm.

Can you use 18 gauge wire for 120v?

The resistance of 18 AWG copper wire is 0.0064 ohms per foot. If you apply 120v from a sufficiently robust power supply end to end on a one foot long piece of such wire 18,750 amps will flow until the wire gets hot enough to melt.

What voltage can 18 gauge wire handle?

The rating of the wire will typically be stamped on the outside (insulation) of the wire and can be from 12 volts to well over 1,000 volts.

How much current can 16 AWG wire carry?

AWG #16 copper wire has a resistance of 4.016 Ω per 1000 feet, or 4.016 mΩ/foot, or 13.18 mΩ/m. If you need to keep the voltage drop along 1 m of wire to 100 mV or less, then you can’t push more than 7.59 A thru it. If you need to limit the power dissipation to 1 W/foot, then you can’t push more than 15.8 A thru it.

What gauge wire is used in homes?

Wire Gauge The most common sizes you’ll find in residential work are 14-gauge and 12-gauge. Larger appliances such as electric stoves, electric water heaters, electric dryers and central air units will often use 10-, 8- or even 6-gauge wire.

What wire do you use for lights?

Wire Gauges and Uses Wire Use Rated Ampacity Wire Gauge Low-voltage Lighting and Lamp Cords 10 Amps 18 Gauge Extension Cords 13 Amps 16 Gauge Light Fixtures, Lamps, Lighting Runs 15 Amps 14 Gauge Receptacles, 110-volt Air Conditioners, Sump Pumps, Kitchen Appliances 20 Amps 12 Gauge.

What happens if wire gauge is too big?

If a wire gauge is “too big” then it is a lot more expensive and is harder to bend, as well as more difficult to attach with wire nuts or to switches. Other than that, not much of anything.

Can I use 18 gauge wire for a lamp?

Lamp Cord Requirements The 18-gauge wire inside a lamp cord is rated for a maximum current draw of about 5 amps. That’s more than enough for a typical 120-volt lightbulb — or even several of them.

Can you connect 18 gauge wire to 12-gauge wire?

NO don’t ever mix AWG Wire gauges they are different for a reason and the main reason is amperage. Sure it will work but it’s 100% wrong and the #18 gauge wire becomes a fusable link and potential fire hazard. It would be easier to use the #18 wire to pull #12 wire and make it right.

Can I connect 18 gauge wire to 16-gauge wire?

Yes the 16-gauge will work just fine. Make sure your connections are well insulated. P. 14AWG is the minimum legal size usable for AC power wiring in the US.

What is 16 AWG wire used for?

16-gauge are used for light-duty extension cords supporting 13 amps. 14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps. 12-gauge are used in kitchen, bathroom, outdoor receptacles, and 120-volt air conditioners supporting 20 amps.

What is AWG wire used for?

AWG or American Wire Gauge is the US standard measure for the diameter of electrical conductors.

What is 20 AWG wire used for?

The 20 AWG Hook Up Wire is available from Remington Industries in both solid core and stranded types. As part of the lead wire family, hook up wire is used in applications such as control panels, meters, ovens, and internal wiring of computers.

How many amps can 18 gauge wire handle 12v?

18-gauge automotive wire can handle anywhere between 3 and 15 amps, depending on the distance (12.2 ft to 2.4 ft). The shorter the wire, the more current it can handle.
