Wire Cross Sectional Area Calculator
Calculate the total cross-sectional area of a wire by multiplying the cross-sectional area of a single strand (calculated using the formula for the area of a circle) by the number of strands.
The Wire Cross Sectional Area Calculator determines the total cross-sectional area of a wire, which is essential for understanding the wire’s current-carrying capacity and resistance.
This tool is useful for electricians, engineers, and hobbyists working with multi-strand wires, ensuring safe and efficient electrical designs.
Formula:
Cross Sectional Area (Sq mm) = π × (Diameter ÷ 2)² × Number of Strands
