## Unit Information

Hectare
/ˈhɛktɛː,ˈhɛktɑː/
Symbol: ha
Unit System: Non-SI Metric

### What is the Hectare?

Its size is down to its use primary use; that for measuring the size of land.

Circular Mil
/ˈsəːkjʊləˌmɪl/
Symbol: cmil
Unit System: Units For Measuring Wire Gauges

### What is the Circular Mil?

The circular mil is a unit designed specifically to measure the area of a wire with a circular cross section. It has the symbol cmil.

An inch is 1000 mils. This makes the circular mil particularly useful for measuring cross sections of wire as there is no need to use the symbol π so the process is simplified.

A circular mil is a very small unit so not advised to use for large areas!
