## Unit Information

Rood
/ruːd/
Symbol: ro
Unit System: Historic English

### What is the Rood?

The rood is a unit of area used in historic England with the symbol ro.

Its unit size is equal to 1/4 of an acre, 10,890 ft² or 1,012m². A rectangle equal to one furlong in length and one rod in width is one rood in area.

Its use was very important in surveying land because of the ease of conversion into acres from smaller sections 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!
