square millimetres.
AnswerIt depends where you live.
In Britain and Europe, the standard measurement is the square millimetre (mm2)
In North America, circular-sectioned conductors are measured in circular mils (CM) or multiples (e.g. MCM -thousand circular mils). A circular mil is derived from the diameter of the conductor, in mils (thousands of an inch) squared -so it isn't really a true unit of area (as the constant, pi, isn't used), but simply a number that represents an area.

What is a column of air of unit cross sectional area?
A unit cross-section, as defined by the SI system of measurement, is 1 metre2. So a column of air is all the air in a vertical column whose cross sectional area is 1 m2. The exact shape of the cross section is not defined but it is normally circular or a square.A unit cross-section, as defined by the SI system of measurement, is 1 metre2.

What is the difference between cross sectional area and diameter of power cable?
Cross section is the surfave area of the cable if you imagine it cut into ... gauge and diameter are basically the same thing, although the unit of measurement are different.
If they give me the height of a prism and the cross-section area how do I find the volume?
Multiply the cross-section area by the height.
What is gram per millimeter?
It is a unit of measurement for linear density. It is usually used for objects with a constant and small cross-sectional area such as bars, rods or wires.
Why are wires with less cross sectional area are used in circuit?
Wires with less cross sectional area are easier to bend and curve around in a circuit. Also, copper costs money, so the more cross-section, then more copper and the cost of building the circuit goes up. Weight savings would be another factor. The maximum expected current load of a section of circuit is calculated, and the size wiring, necessary to handle that current is used.
How do you find volume of a box with uniform cross section if only height is given?
You need to know the area of that cross-section. Once you have that number, the volume of the box is the product of (cross-section area) x (height).
What is the formula for cross section area for square?
The formula for cross section area of a square is very easy to use. Measure the length of one side of the square it. If you are doing the cross section area of a rectangle, measure both sides and multiply them together.
What gauge wire are 4 24 gauge wires equal to?
Look up a wire table on google. The table tells you the cross-section area area of the 24 g wire. Multiply that by 4 then find the gauge that gives the new cross-section. A 24 AWG wire has a cross-section of 0.205 sq.mm. Four of those have a c/s area of 0.82 sq. mm. so the nearest equivalent wire is 21 AWG at 0.81 sq. mm.
Volume and surface area of prisms a?
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
How you find the volume of a trapezoidal 3D section?
Volume = area of cross-section*length
How do you figure size of wire required for a circuit?
The size of wire depends on the amount of current it has to take. The size of the wire is measured by its cross-section area, and also in wire gauges. A useful limit for wires that are used occasionally in the house is 10 amps per square millimetre of cross-section (of one of the wires). For continuous loads the rating is less, 2-3 amps per sq. mm.
What is a meant by cross section?
Imagine that you wanted to cut a globe or a sphere exactly in half. When you looked at the cut you would see an exact circle on both pieces. This area would be the cross-section. You could work out the area of this cross-section by using A = Pi X r squared. But be careful. Don't assume that the cross sectional area is the same no matter where you cut. If you cut the globe at some other point, say near to the edge, the cross-section (the circular area that you would see) would be a lot smaller. You would come across a uniform cross-section if you cut a cable. No matter where you cut the cable the cross-section should be roughly the same. Also cross section doesn't have to be circular. The cross-section you get really depends on the original shape you are dealing with. If you cut a cube in half, you would get a square cross-section. So I guess you could imagine the term as applying to cutting across (hence cross) something to reveal 2 sections (hence section).
