What is 1 square metre in square feet?

1 square metre = approximately 10.7639 square feet. The calculator does the conversion automatically and also displays the result in square yards, acres and hectares.

How do I find the area of an L-shaped room?

Split the room into two rectangles, calculate the area of each, then add the two together. The calculator allows you to add multiple shapes by computing each separately and summing the results.

1 acre = 4,046.86 square metres = 43,560 square feet = 0.4047 hectares. About the size of a UK football pitch (without end zones).

Om kvadratmeter-lommeregneren

The Square Footage Calculator works out the area of any room, floor or plot of land and converts the result into the unit you need. It supports four common shapes — rectangle, triangle, circle and trapezoid — and accepts measurements in metres, feet or feet + inches.

Formulas used

Rectangle: Areal = length × width
Triangle: Areal = ½ × base × perpendicular height
Circle: Areal = π × radius²
Trapezoid: Areal = ½ × (side a + side b) × perpendicular height

Unit conversions

Lommeregneren viser resultatet i seks almindelige enheder. De nøjagtige konverteringer er:

1 m² = 10,7639 ft² = 1,19599 yd² = 1.550 tommer²
1 acre = 4,046.86 m² = 43,560 ft² = 0.4047 hectares
1 hectare = 10,000 m² = 2.4711 acres

Sådan måler du et rum eller gulv

Use a tape measure or laser to find the length and width.
Take measurements at floor level, ignoring skirting boards but including alcoves.
For irregular shapes, split the room into rectangles and add their areas.
Konverter alle fod-og-tommer aflæsninger ved hjælp af lommeregnerens "Fødder + Tommer" tilstand.

Common uses

Estimating flooring (carpet, tiles, laminate, vinyl) — buy 5–10% extra for cuts and waste
Køb af maling — de fleste mærker angiver dækning per liter eller gallon (m² eller ft²) på dåsen
Property listings — UK floorplans often quote total internal area in ft² and m²
Garden and land sizing — convert to acres or hectares for plot deeds
Heating/cooling sizing for HVAC, radiators or air conditioning

Ofte stillede spørgsmål

How do you calculate square footage? For a rectangle, multiply length by width. For other shapes, use the formulas above. The calculator handles all four automatically.

What is 1,000 ft² in square metres? 1.000 ft² ≈ 92,9 m². Skriv 1.000 i et rektangel i fødder (med 1 som den anden side) og m²-resultatet vises straks.

Why does my measurement seem too big? Dobbelttjek enhederne — fødder og meter er nemme at forveksle. Et "5 gange 4" rum er 20 m² (≈ 215 ft²) i meter men kun 20 ft² (≈ 1,86 m²) i fødder.

Does the calculator handle L-shapes? Not directly. Split the L into two rectangles, calculate each, and add the results.

Is my data stored? No — every calculation runs locally in your browser.
