How do I calculate square meters from length and width?

Multiply length by width, after converting both to the same unit. If measurements are in different units (say, one in feet and one in meters), convert both to meters first, then multiply.

How do I convert square feet to square meters?

Multiply the square feet value by 0.092903 to get square meters, since one square foot equals approximately 0.092903 square meters.

Square Meters Calculator — Area & Unit Conversion

How area is calculated

Area of a rectangle is simply length times width, once both measurements are in the same unit.

area = length × width

This tool lets length and width use different units — it converts both to meters internally first, multiplies, then converts the result to whichever output unit you select.

Common conversion factors

1 ft² = 0.092903 m² 1 yd² = 0.836127 m² 1 m² = 10,000 cm² 1 hectare = 10,000 m²

Common uses

Flooring and tiling: figuring out how much material to order for a room.
Real estate: comparing property listings that use different unit systems.
Land and lots: converting between square meters and hectares for larger areas.
Painting and landscaping: estimating coverage needed for a wall or yard.

Frequently asked questions

Can I mix units between length and width?

Yes — each field has its own unit selector, and the calculator converts both to a common unit before multiplying, so entering length in feet and width in meters works correctly.

Does this work for non-rectangular areas?

This calculator assumes a rectangle. For an L-shaped or irregular area, split it into rectangular sections, calculate each one separately, and add the results together.
