Wire Cross Sectional Area Calculator

First find the diameter of the wire.
Wire cross sectional area calculator. A d 2 π 4 0 7854 d 2. The formula to find the cross sectional area of the wire in square millimeters is. Second multiply the diameter by 1000 to find the area in kcmil or by 3 1415 4 to calculate square millimeters.
This calculator determines the wire s cross sectional area based on the number of strands and individual strand diameter. Circular mils input awg number here. Use the formula above to calculate the width if the awg is known.
A wire size chart can be found here. Wire cross sectional area calculations the n gauge wire s cross sercional area a n in kilo circular mils kcmil is equal to 1000 times the square wire diameter d in inches in. Telephone wire is usually 22 24 or 26.
Click here to view our metallic area elastic stretch calculator. This calculates the metallic cross sectional area in a rope and then uses this information to calculate elastic stretch in a rope that occurs under load. The cross section area of a round single wire can be calculated as.
The cross section area of bunched wires can be calculated as. Metallic area elastic stretch calculator. D single wire.
Typical household copper wiring is awg number 12 or 14. A n d 2 π 4 0 7854 n d 2. The cross section of a cable wire should be selected to match the current consumption of the connected loads.
