Square Feet to M² Converter
Quick Answer
1 square foot (ft²) equals 0.09290304 square meters (m²). To convert square feet to square meters, multiply the area in ft² by 0.09290304. For example, 100 ft² × 0.09290304 = 9.290304 m².
The Square Feet to M² Converter converts an existing area measurement from square feet (ft²) into square meters (m²) without requiring you to calculate the area again. Enter the known square footage, and the converter returns the equivalent metric area using the standard square foot to square meter conversion factor.
For a rectangular room, floor, wall, property section, patio, flooring project, or other measured surface, the area is normally determined from length × width before conversion. Length represents one side of the measured surface, while width represents the other side. Height is not required for an area conversion unless you are calculating volume or another three-dimensional measurement.
Use the converter when a measurement is provided in square feet but you need the result in square meters for flooring, construction, renovation, real estate, room measurements, architectural plans, material estimates, or metric-based project calculations. The reverse m² to ft² option is available when a metric area needs to be converted back to square feet.

Square Feet to Square Meters Formula
The square feet to square meters conversion uses a fixed area conversion factor. NIST lists one square foot as 0.09290304 square meters. :contentReference[oaicite:1]{index=1}
Conversion Formula
To convert ft² to m², multiply the number of square feet by 0.09290304. To convert m² back to ft², multiply the number of square meters by approximately 10.7639104.
Square Feet to M² Conversion Example
A rectangular room measuring 10 feet in length and 10 feet in width has an area of 100 square feet. The height does not affect the floor area because this conversion works with two-dimensional area.
Example: 100 ft² to m²
100 ft² × 0.09290304 = 9.290304 m²
Helpful Information Before You Convert
Use the correct type of measurement before entering a value because square feet and square meters measure area, while feet and meters measure length.
Use Area Measurements
- Enter ft² when the known measurement is square footage.
- Enter m² when the known measurement is square meters.
- Convert length and width into an area measurement before using this tool when only dimensions are available.
- Keep the unit consistent when calculating a rectangular floor, room, patio, wall, or surface area.
Length, Width, and Height
- Measure length along one side of the surface.
- Measure width along the second side of the surface.
- Multiply length × width to obtain square feet or square meters.
- Ignore height for a basic area conversion because height is used for volume rather than two-dimensional surface area.
Common Applications
- Estimate floor area for flooring, tile, carpet, laminate, and vinyl projects.
- Convert property or room measurements between imperial and metric units.
- Compare construction quantities measured in square feet with specifications listed in square meters.
- Calculate material costs when a supplier provides a price per ft² or m².
Cost Estimation
The optional cost estimator can calculate an approximate project cost from a price per square foot or price per square meter. For example, an area of 500 ft² priced at $4.00 per ft² produces an estimated material cost of $2,000.00. Labor, waste, delivery, taxes, preparation, installation, and project-specific charges are not automatically included.

How many square meters are in 1 square foot?
1 square foot equals exactly 0.09290304 square meters. Multiply any area measured in ft² by 0.09290304 to obtain the equivalent area in m².
How do I convert square feet to square meters?
Multiply the square-foot value by 0.09290304. For example, 500 ft² × 0.09290304 = 46.45152 m².
How do I convert square meters to square feet?
Multiply the square-meter value by approximately 10.7639104. For example, 50 m² is approximately 538.1955 ft².
Do I need length and width to use this converter?
No. The converter requires an existing area measurement in ft² or m². Length and width are required only when you first need to calculate the area of a rectangular surface.
Is height required for square feet to square meters?
No. Height is not required because square feet and square meters measure two-dimensional area. Height becomes relevant when calculating volume in cubic feet or cubic meters.
What is the difference between ft² and m²?
ft² means square feet, an imperial or U.S. customary area unit, while m² means square meters, the SI (International System of Units) area unit. One ft² equals 0.09290304 m².
Can this converter help estimate flooring costs?
Yes. Enter the known floor area and use the optional cost estimator with a price per ft² or m² to calculate an estimated material cost. Include waste, installation, labor, delivery, taxes, and other project charges separately when preparing a complete budget.
What is 100 square feet in square meters?
100 square feet equals 9.290304 square meters. The calculation is 100 × 0.09290304 = 9.290304 m².
