*Metric units rounded out

Did you know?

1. The perch was first standardised in England around the 14^th century by the statute called The Composition of Yards and Perches.

2.  The rod sometimes gets confused with the rood. The rood is a unit of area (= 0.10 hectares / 1 012m^{2 /} 10 890 sq ft) as well as an archaic English unit of length.

In fact, historically rod had the same meaning as rood. There are written records of the term rod was used interchangeably with rood.

3. The term “rod” has been more popular than “perch” since the 15^th century. However, the word “perch” is still in use as a customary term.

What about you? Would you rather call the unit “rod” or “perch”?
