# Conductivity vs. Conductance: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 27, 2024
Conductivity is a material's ability to conduct electricity, measured in Siemens per meter (S/m), while conductance is the measure of how easily electricity flows through a specific component, measured in Siemens (S).

## Key Differences

Conductivity refers to a material's inherent ability to allow the flow of electric current, dependent on its composition. In contrast, conductance is a specific measure of how easily electricity passes through a particular object or component.
