Square Feet to Square Meters: Conversion Guide

The Conversion Factors

There are only two numbers to remember, one for each direction.

So a 500 square foot room is 500 × 0.0929 = 46.45 square metres, and a 30 square metre flat is 30 × 10.764 = 322.9 square feet. The exact figure is 10.7639 square feet per square metre, but 10.764 is precise enough for any real-world purpose, and 10.76 is fine for a quick estimate. If you ever forget which way to multiply, use common sense as a check: a square metre is bigger than a square foot, so a figure in square feet is always a larger number than the same area in square metres.

Why You Square the Number

This is the part worth understanding, because it explains why the area factor looks unrelated to the length factor.

One metre equals 3.281 feet. That is a length, a single dimension. But area is length times width, two dimensions, so when you convert an area you convert each dimension. Picture a square that is one metre on each side. In feet, that same square is 3.281 feet by 3.281 feet, and its area is 3.281 × 3.281 = 10.764 square feet. The conversion factor gets squared because the shape has two directions, both of which shrink or grow when you change units. The same logic runs through volume, where you cube the factor instead: one cubic metre is 3.281 × 3.281 × 3.281, about 35.3 cubic feet. Our guide on converting metric and imperial units covers this squaring-and-cubing rule across all the common conversions.

Worked Examples

A few in each direction, so the method sticks.

Square feet to square metres. A 1,200 sq ft apartment is 1,200 × 0.0929 = 111.5 m². A small 120 sq ft bedroom is 120 × 0.0929 = 11.15 m². A 350 sq ft studio is 350 × 0.0929 = 32.5 m².

Square metres to square feet. A 25 m² room is 25 × 10.764 = 269.1 sq ft. A 90 m² house is 90 × 10.764 = 968.8 sq ft. A 4 m² bathroom is 4 × 10.764 = 43.1 sq ft.

Notice how a 1,200 sq ft home comes out near 111 m², not near 366, which is what you would wrongly get using the length factor of 3.281. If a conversion ever gives you a number that feels three times too big or too small, the squared-versus-linear mix-up is the first thing to check.

Where This Comes Up

The conversion matters most when two people are using different systems for the same space, which happens constantly with property.

Property listings are the big one. A flat advertised as 1,000 square feet in one country and 93 square metres in another is the same size, and being able to convert lets you compare like with like instead of trusting a vague impression. Flooring, tiling, and carpet are usually sold per square metre or per square foot depending on the region, so converting the room area to the seller’s unit stops you over- or under-ordering. Land area, paint coverage, and even air-conditioning sizing all cross between the two systems. In every case the job is the same: get both figures into one unit before you compare or buy.

Common Mistakes

• Using the length factor 3.281 for area instead of the squared factor 10.764. This is by far the most common error and inflates or shrinks the result by roughly three times.
• Multiplying when you should divide, or the reverse. Sanity-check with size: square feet always give a bigger number than square metres for the same area.
• Converting each side of a room separately and then multiplying, which works but invites arithmetic slips; convert the finished area instead.
• Mixing units mid-calculation, such as a length in feet and a width in metres. Convert to one system before multiplying.
• Over-rounding early. Keep a couple of decimals until the final answer, especially on large areas where small errors add up.

Frequently Asked Questions

How do I convert square feet to square meters?

Multiply the number of square feet by 0.0929, or equivalently divide by 10.764. For example, 500 square feet is 500 times 0.0929, which is 46.45 square metres. To convert the other way, multiply square metres by 10.764. These two factors handle every square-feet-to-square-metres conversion in both directions.

How many square feet are in a square meter?

One square metre equals 10.764 square feet (10.7639 to be exact). It comes from squaring the length conversion: one metre is 3.281 feet, and 3.281 multiplied by itself is 10.764. Use 10.764, not 3.281, whenever you are converting area rather than a single length.

Why isn’t the area conversion just 3.281?

Because 3.281 converts length, a single dimension, while area has two dimensions. A one-metre square is 3.281 feet on each side, so its area is 3.281 times 3.281, which is 10.764 square feet. Whenever a unit is squared, as in square feet, the conversion factor is squared too. Volume, being cubed, uses the factor cubed.

What is 1000 square feet in square meters?

1,000 square feet is about 92.9 square metres (1,000 times 0.0929). A common quick check: divide the square feet by roughly 10.76 to get square metres, so 1,000 divided by 10.76 is about 92.9. This is a typical size for a modest apartment or a large open-plan room.

How do I convert square meters to square feet?

Multiply the square metres by 10.764. For example, 75 square metres is 75 times 10.764, which is 807.3 square feet. Because a square metre is larger than a square foot, the square-foot figure is always the bigger number, which is a handy way to confirm you multiplied in the right direction.

Is a square meter bigger than a square foot?

Yes, much bigger. One square metre is about 10.76 square feet, so a square metre is nearly eleven times the area of a square foot. That is why converting an area from square metres to square feet always produces a larger number, and converting the other way produces a smaller one.

Do the same rules apply to volume?

Yes, but you cube the factor instead of squaring it. Since one metre is 3.281 feet, one cubic metre is 3.281 cubed, about 35.3 cubic feet. The principle is the same across units: square the length factor for area, cube it for volume, because each extra dimension multiplies the conversion in again.

The Bottom Line

Square feet to square metres is a multiply by 0.0929; square metres to square feet is a multiply by 10.764. The one rule that prevents the biggest error is remembering that area squares the length factor, so it is 10.764 and not 3.281. Convert to a single unit before you compare property sizes or order flooring, and sanity-check the direction against the fact that square feet always give the larger number. For areas beyond a simple rectangle, the area calculator does the measuring and the conversion at once.
