Resistivity

Conductivity, often represented using sigma,, is the inverse of resistivity: = 1/ . Conductivity is given in units of Siemens per metre, or S/m. Units of millisiemens per metre (mS/m) are often used for small conductivity values; 1000mS/m = 1S/m. So 1mS/m = 1000 Ohm-m, since resistivity and conductivity are inversely related.
