Formula and Maths
Why is the conversion factor 10.7639?
One metre equals exactly 3.28084 feet (per the 1959 international yard and pound agreement). Since area is two-dimensional, you square the linear factor: 3.28084 x 3.28084 = 10.76391041671. Rounded to 10.7639 for display.
How do I convert square metres to square feet?
Multiply by 10.7639. For a quick mental estimate, multiply by 11 and subtract 2-3%. The formula is: ft2 = m2 x 10.7639.
How do I convert square feet to square metres?
Divide by 10.7639. Equivalently, multiply by 0.0929. The formula is: m2 = ft2 / 10.7639.
How do I calculate square metres of a room?
Measure length and width in metres and multiply. For a room 4.5 m x 3.2 m: 4.5 x 3.2 = 14.4 m2. For L-shaped rooms, split into rectangles and add the results.
What is a quick mental shortcut for m2 to sq ft?
Multiply by 11 and subtract 2-3%. For 80 m2: 80 x 11 = 880, subtract 19 (2.2%) = 861. Exact answer: 861.11. The shortcut is within 0.2% for most values.

Commercial Space
How much office space per person in m2?
Industry standards range from 8-10 m2 per person for dense open-plan hot-desking, to 10-12 m2 for standard assigned-desk offices, to 18-25 m2 for premium layouts with private offices and generous breakout space.
How much office space do I need for 10 people?
At standard open-plan density (11 m2 per person), 10 people need approximately 110 m2 (1,184 ft2). At premium density (20 m2 per person), you would need 200 m2 (2,153 ft2). Use the calculator on the commercial space page for your exact scenario.
How is office space measured commercially?
Commercial leases typically quote Net Internal Area (NIA), which excludes structural walls, columns, stairwells, and mechanical rooms. Gross Internal Area (GIA) includes these. NIA is typically 80-90% of GIA. When comparing leases, always confirm which measure is being used.
Land Measurement
How many square feet is a hectare?
1 hectare = 107,639 square feet. A hectare is 10,000 m2, and since 1 m2 = 10.7639 ft2, 10,000 x 10.7639 = 107,639 ft2.
