# CCS vs solid copper weight & cost calculator

> Weigh a CCS conductor against solid copper at the same diameter, show the copper the cladding delivers, and price both builds from your own price per kilogram.

## Formula

CCS weight = area × [v·8.89 + (1−v)·7.85] g/cm³; solid-copper weight = area × 8.89 g/cm³. Copper content = area × v × 8.89. Copper-equivalent diameter = D × √v.
Cost per km = copper mass × your Cu price + steel mass × your steel price. Raw-material only; cladding and processing excluded.
