# ohms per square

## Definition

### Electronics

- A measure of the resistance between parallel edges of a thin film resistive material, such as a
__metal__ or semiconductor. The resistance of a four-sided material is defined as the resistance, in ohms, multiplied by its width, and divided by its length. Since the length and width of a square are __equal__, the measured resistance value will be the same for any size square. The resistance of such a material could then be stated in ohms, but in this context is expressed in units of ohms per square.
