About these units
Square Chain (ch²)
A square chain equals the area of a square one chain (~66 feet) per side, resulting in 4,356 square feet, or exactly 1/10 of an acre. This unit is closely linked to the chain, a surveyor's unit standardized by Edmund Gunter in the 17th century. Because 10 square chains make an acre, survey calculations for early colonial and American lands were extremely efficient. Square chains allowed surveyors to map and divide land rapidly using ropes or metal chains, producing a legacy seen in long, straight property lines still visible today across rural landscapes.
Rood (rood)
A rood equals 1/4 of an acre, or 10,890 square feet, and was used in medieval and early modern England for land measurement. The rood often appeared in agricultural records, taxation documents, and estate descriptions. Farmers used the rood to describe smaller plots of arable land, orchards, and grazing fields. Although obsolete today, the rood reflects the practical needs of historical agrarian societies, where manageable sub-acres allowed fine-grained recordkeeping and land division within larger estates.
