ストーンをキログラムに換算するには？
ストーンの数に 6.35 を掛けます。11 st 4 lb のような表記は 11 ストーン 4 ポンドという意味なので、ストーンを換算したうえでポンドに 0.4536 を掛けた値を足します。
キログラム = ストーン × 6.35029ストーン = キログラム ÷ 6.35029
この二つの単位が使われる場所
ストーンが 14 ポンドに定まったのは 1835 年の英国度量衡法からで、それまでは業種ごとに異なり、肉なら 8 ポンド、羊毛なら 14 ポンドでした。今日では人の体重にしか使われません。 キログラムは接頭語を名前に残す唯一の国際単位系基本単位であり、2019 年からは白金の分銅ではなくプランク定数によって定義されています。 ストーンは 14 ポンド、6.35 キログラムで、いまでは英国とアイルランドの体重にしか残っていません。医師はキログラムで記録し、患者はストーンで考えます。

よくある質問
1ストーンは何キログラムですか？
1ストーンは 6.35029318 kg、つまり 14 ポンドです。ポンドの定義から導かれるため、この値は正確です。
英国では体重をストーンで量るのはなぜですか？
メートル法への移行後も残った生活習慣です。診療記録ではキログラムが使われますが、会話や家庭用体重計ではストーンのほうがよく登場します。
11 st 4 lb はどう読みますか？
11 ストーン 4 ポンドという意味で、11 × 6.35 + 4 × 0.4536 = 71.67 kg です。ポンドの部分はつねに 14 未満で、14 に達すると 1 ストーンに繰り上がります。
11.4 ストーンが 11 ストーン 4 ポンドにならないのはなぜですか？
1 ストーンが 10 ポンドではなく 14 ポンドだからです。小数部分は 14 分の何かを表し、0.4 ストーンは 5.6 ポンドにあたります。つまり 11.4 st は 11 ストーン 5.6 ポンド、72.4 キログラムです。一方 11 st 4 lb と書かれた体重は 158 ポンド、71.7 キログラムです。二つの書き方は 700 グラム違いますが、その取り違えを知らせるものは何もありません。
米国でも体重をストーンで量りますか？
いいえ、体重には決して使いません。同じ人について、米国人は 160 ポンドと言い、英国人は 11 ストーン 6 ポンドと言います。ストーンは 1985 年に英国の商取引から外されましたが、日常の会話や診察室、家庭の体重計には残りました。画面の世界にインチが残ったのと同じことです。
