Volume and surface elements in different co-ordinate systems

From Wikipedia, the free encyclopedia

This page outlines the value of different volume and surface elements in several different co-ordinate systems.

System Volume Surface
Cartesian dV = dxdydz dS = dxdy
Cylindrical dV = ρdρdφdz dS = rdθdz
Spherical dV = r2sinθdrdφdθ dS = r2sinθdφdθ
