Read the unit before the number
One hectare is 100 ares, and one are is 100 square metres. Read the printed column heading before converting an extent: the specimens linked below use a combined hectares–ares field or separate hectare, are and square-metre columns. They are different properties, so their figures illustrate the notation rather than a mismatch in one parcel’s area.
Patta and A-register: 0–2.22
The matching patta and A-register samples print 0–2.22 under hectares–ares. That means 0 hectares and 2.22 ares: 222 square metres. It is not 2.22 hectares, which would be 22,200 square metres. Keep the original figure and its heading beside any converted area. See the patta’s extent heading
FMB: Hect 01 Ares 82.00
The FMB sample prints “Hect 01 Ares 82.00” in its header. One hectare plus 82 ares is 182 ares, or 18,200 square metres. The drawing has a boundary with several measured segments; multiplying two selected edge lengths would not reproduce that irregular outline’s area. Read the FMB sample’s area header
TSLR: three separate columns
The TSLR sample separates Hectare, Ares and Sq. Meter. Its entries are 0, 0 and 94.0, so the recorded extent is 94 square metres. A house-site entry can therefore use metric columns too; read the actual headings rather than choosing a unit from the property’s postal address. See the TSLR extent columns
Comparing cents, grounds and square feet
One cent is one-hundredth of an acre: 435.6 square feet, or about 40.47 square metres. If a quote uses a ground of 2,400 square feet, that converts to about 222.97 square metres; confirm the convention used in that quote. Neither cents nor grounds is printed on the specimens discussed above. Label a conversion separately from the source extent, and compare figures only after putting them in the same unit.
