Square Feet to Square Meters Converter
This tool converts U.S. area measurements to metric using the Square Feet to Square Meters Converter. It’s helpful when reviewing real-estate listings, comparing renovation quotes, sizing flooring or turf, or collaborating with teams and suppliers who work in square meters.
Type in an area and get an instant metric equivalent so plans, bids, and purchase estimates stay consistent across documents. The goal is fast, reliable unit translation that reduces math errors and makes it easy to communicate room sizes, project scopes, and material needs with anyone—no formulas required.
Convert ft² and m² with instant accuracy — plus quick room presets and optional waste buffer.

Square Feet to Square Meters Results
Results interpretation
- Waste buffer: flooring, tile, or fabric installs often need 5–15% extra to cover cuts and pattern match.
- Rounding: display rounding doesn’t change the underlying math; adjust to match supplier quoting precision.
- Estimating: prefer measuring each wall or zone and summing areas if rooms are irregular.
How ft² ⇄ m² conversion works
Formulas, steps, and assumptions
Formulas: m² = ft² × 0.09290304 (exact); ft² = m² ÷ 0.09290304.
Waste: areawaste = area × (1 + waste%).
Steps: enter ft² or m² → choose rounding → set waste if needed → copy a shareable link with your inputs.
Assumptions: planar surfaces; no deductions for fixtures unless you subtract them from input area.
Use cases & examples
Example 1 (flooring): 300 ft² with 10% waste → 330 ft² total; that’s 27.87 m² → 30.66 m² with waste.
Example 2 (apartment area): 75 m² → 807.29 ft².
Example 3 (room preset): 12×15 ft → 180 ft² → 16.72 m².
Square feet to square meters — FAQ
How do I convert ft² to m²?
Multiply square feet by 0.09290304 (exact). Example: 250 ft² × 0.09290304 ≈ 23.23 m².
How do I convert m² to ft²?
Divide square meters by 0.09290304 (or multiply by 10.7639104).
What waste percentage should I use?
For simple rooms, 5–8% is common. For complex patterns or lots of cuts, 10–15% is safer.
Does rounding affect my final order?
We round only for display. Still, vendors sell in carton/batch sizes—round up after adding waste.
Can I subtract doors or cabinets?
Yes—measure areas you won’t cover and subtract them before converting.
Is 0.09290304 exact?
Yes. 1 foot = 0.3048 m exactly, so 1 ft² = (0.3048)² m² = 0.09290304 m².
Area conversions in real projects
We convert ft² and m² using exact constants so orders and quotes align across metric and imperial markets. Adding a modest waste buffer helps prevent short orders and extra trips—especially with patterned materials or complex layouts.
Choosing a waste percentage
For simple rectangular rooms, 5–8% often suffices. Herringbone or diagonal patterns can require 10–15% due to cuts. Always check vendor guidance.
Measuring tips
Break irregular spaces into rectangles, compute each area, and sum. Subtract large openings if they won’t be covered.
Rounding for ordering
Many products are sold in fixed carton sizes; round up to the next whole carton after adding the waste buffer.
