How the calculation works

1 perch = 272.25 square feet = 25.29285264 square metres. 1 rood = 40 perches; 1 acre = 4 roods = 160 perches. One hectare is 10,000 m²; one cent is 1/100 acre. Results use exact unit factors, then display rounding.

Area conversion is not a land survey. Check the actual extent, boundaries and legal description with a licensed surveyor.

Reference and verification

NIST publishes the exact international-foot square-perch and acre factors. Sri Lanka Survey Department is the appropriate authority for cadastral records.
