Compare land asking prices
Use the extent above for Plot A. Enter your own asking price; compare a second listing on the same price basis.
Asking-price arithmetic only. Location, access, title, surveying, taxes, legal fees and development costs are not included. A lower unit price does not establish better value.
How the calculation works
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.
