Convert between eleven area units at once — imperial, metric and South Asian land measures, with the marla standard left in your hands.

This converter takes one area figure and shows it in every unit we support at the same time: square feet, square metres, square yards, square inches, square centimetres, acres, hectares, square kilometres, square miles, marla and kanal. You do not have to run it twice — enter the number once and read the row you need.
Area conversion trips people up for one reason: most units are fixed by international definition, but a few are not. An acre is always 43,560 square feet and a hectare is always 10,000 square metres, everywhere on earth. A marla is not. It is a traditional unit that different regions and different housing societies define as 272.25, 250 or 225 square feet, so the same advertised plot can differ by more than 20% depending on whose definition you use. That is why this tool asks you to choose a marla standard instead of quietly assuming one.
To convert, multiply by the factor for the target unit
The calculator converts your input to square feet first, then divides by the factor of every other unit. Square feet is the common meeting point because the imperial and South Asian land units are defined in it, and the metric units convert to it exactly.
Kanal is defined as exactly 20 marla wherever it is used, and traditionally as 605 square yards — 5,445 square feet. Kanal therefore has a fixed square-foot value and no selector.
Marla is the variable one. In traditional revenue records and older city schemes it is 272.25 square feet (30.25 square yards), which is what makes 20 marla equal a 5,445 square foot kanal and 8 kanal equal an acre. In many newer housing societies a marla is rounded to 250 square feet, and some regions and older schemes use 225 square feet. If you are buying or selling land, confirm the standard in writing before you agree a price.
You are comparing two listings: one plots out at 1,200 square feet and the other at 111 square metres. Enter 1,200 with the from-unit set to square feet and the result is 111.484 square metres — so the two plots are the same size, give or take a rounding difference in the listing.
Now enter 10 with the from-unit set to acres. The table returns 4.0468564 hectares, 43,560 square feet, 4,840 square yards, 160 marla and 8 kanal — the last two only at the 272.25 square foot marla standard. Switch the marla standard to 250 and the same acre reads 174.24 marla.
Square feet dominates residential floor area in the United States, the United Kingdom, India, Pakistan and the Gulf. Square metres is the standard for construction drawings and floor plans almost everywhere else, and for any engineering document. Acres cover rural and development land in the US, UK, Ireland and the Commonwealth; hectares do the same job in most of Europe, Latin America, Africa and Asia. Marla and kanal are the working units of residential plot markets in Pakistan and parts of northern India.
