Note 16 — Chapter VI · LAND-MEASURES
Reading edition
It is worth remark that the 160 square rods of the Irish, Lancashire or Guernsey acre being equal to 1·62 statute acres, 100 of these square rods would make almost exactly a statute acre. A rod of 6·957 yards would give a decimal square rod of 48·4 square yards equal 1-10th square chain, or 1-100th acre, or 1-1000th square furlong. A square-shape acre is 69·57 yards square.
