平方フィートを平方メートルに換算するには？
平方フィートの面積を 10.764 で割ります。暗算では 10 で割ってから 7 % を引きます。1,000 sq ft なら 100 − 7 = 93 m² となり、ぴたりと合います。
平方メートル = 平方フィート × 0.0929平方フィート = 平方メートル × 10.764
この二つの単位が使われる場所
平方フィートは米国と英国の不動産広告の単位であり、アジアのいくつかの市場ではオフィス賃貸契約の単位でもあります。 平方メートルはほとんどの国で居住面積を表し、メートル法が行き渡る地域では不動産価格の基準になっています。

1 平方フィートは正確に 0.09290304 m² です。1959 年の協定により国際フィートが 0.3048 メートルと定義されているためです。 算出方法と出典.
よくある質問
1平方フィートは何平方メートルですか？
1平方フィートは 0.0929 平方メートル、つまり一辺 30.48 cm の正方形にあたります。逆に 1 m² には 10.76 平方フィートが収まります。
2,000平方フィートの米国住宅は広いですか？
186 m² で、ヨーロッパの平均を大きく上回ります。米国の新築住宅の中央値はおよそ 2,300 sq ft、つまり 214 m² で、日本の一戸建ての延床面積の平均 120 m² 前後よりかなり広くなります。
長さのように 3.28 で割ってはいけないのはなぜですか？
面積は長さ2つの積なので、係数が2乗されるからです。3.2808 の2乗は 10.764 です。3.28 で割ると 3 倍以上大きい答えになってしまいます。
香港とシンガポールが平方フィートで売るのはなぜですか？
英国由来の慣行で、ほかはすべてメートル法の二都市に残ったものです。落とし穴は換算ではなく定義にあります。香港はかつて、共用部分の持ち分を含む総床面積と、実際に住める実用面積を区別していました。2013 年以降、新築の販売では実用面積の表示が義務づけられており、それはかつての総床面積より 4 分の 1 ほど小さいことも珍しくありません。
部屋のタイルはどれだけ買えばよいですか？
平方フィートで数えるのは北米の流儀で、箱に記された施工可能面積がその単位です。12 平方メートルの部屋は 129 平方フィートですから、1 箱 15 平方フィートなら 9 箱要ります。切断のぶんとして 1 割、斜め張りや部屋が長方形でない場合は 1 割 5 分を上乗せしてください。ロットが尽きたあとで端材を取り戻すことはできません。
