# How To Measure Cross Sectional Area Of Cable

**The crosssection area is just that.**

**How to measure cross sectional area of cable**.
The cross section area of a round single wire can be calculated as.
0 75 mm 2 1 5 mm 2 2 5 mm 2 4 mm 2 6 mm 2 10 mm 2 16 mm 2.
A cross section area mm 2 in 2 d diameter mm in cross section area of bunched wire.

Calculate cross section and conversion factors for cables and wires current carrying capacity. D 2 r diameter of the wire or cable. R radius of the wire or cable.

N number of wires. S πd2 4 to get the area of a single strand s n s to get the approximate area of a number of strands where. A n d 2 π 4 0 7854 n d 2.

The cross section area of bunched wires can be calculated as. S area of a single strand d diameter of a single strand p 3 14 s area of defined no. 11 17 18 21 26 and 27.

Or if you have micrometers measure diameter half it to get radius and then do pi r2 or cut a bit off and hold it up to the reels in band q and se what it is the same as. A d 2 π 4 0 7854 d 2. With the radius we can calculate.

To calculate the cross sectional area csa of a cable you have to use a micrometer to verify its diameter then divide the diameter by two to get the radius r. Measure area of circle with calibrated graticule microscope or similar. D single wire diameter mm in diameter of a single wire cross section area.
