メートル法（メートルほう、英：metric system [1][2][3]、仏：système métrique）とは、長さの単位であるメートル（フランス語: mètre）と質量の単位であるキログラム（仏：kilogramme）を基準とする、十進法による単位系のことである[4][5][6][7][8][9][10][11][12]。, メートル法は、18世紀末のフランスにおいて、世界で共通に使える統一された単位制度の確立を目指して制定された。当時の世界には同じ物理量に対して様々な単位があり、しかも同じ単位系の中でも、複雑な換算を必要とする単位が併用されているものもあった。人間の行動範囲が狭い間は、その地域だけで単位が統一されていれば良かったが、人間の行動範囲が広くなり、グローバリゼーションで商取引等が行われるようになると、単位の不統一が大きな問題となってきた。, そこで、フランス革命後の1790年3月に、国民議会議員であるタレーラン＝ペリゴールの提案によって、世界中に様々ある長さの単位を統一し、新しい単位を創設することが決議された。それを受けて1791年に、地球の北極点から赤道までの子午線弧長の「1000万分の1」として定義される、新たな長さの単位「メートル」が決定された（これにより地球の円周が4万キロメートルとなるように定義されたが、地球は厳密には真球ではなく回転楕円体に近い形をしているので、実際にはやや誤差がある）。, なお、この時の測量はダンケルクからバルセロナの距離を経線に沿って三角測量で測定し、その値を元にして計算が行われた。質量も、このメートルを基準として、1立方デシメートルの水の質量を1キログラムと定めた（正確な定義はそれぞれの単位の項目を参照のこと）。他に、面積の単位としてアール（are, 100平方メートル）、体積の単位として乾量用のステール（stere, 1立方メートル）と液量用のリットル（litre, 1立方デシメートル）を定めた。, フランスにおいても、既に使われていた単位系があったため、使用には反対が多く、すぐには普及しなかった。結局1837年に「1840年以降はメートル法以外の単位の使用を禁止する」旨の法律が出され、公文書にメートル法以外の単位を使用した場合は罰金が科せられることとなり、普及することになった。, フランス以外の国家でも、度量衡の単位の統一に悩んでおり、メートル法に興味を持ち始めた。1867年のパリ万国博覧会の際、パリに集まった学者の団体が、メートル法によって単位の国際統一する決議を行った。1875年、メートル法を導入するため、各国が協力して努力するという主旨のメートル条約が締結された。, ヨーロッパに比較して、アメリカでは連邦政府が努力していないこともあってか、メートル法はほとんど普及しておらず、ヤード・ポンド法が主流である。イギリスでは国内向けにヤード・ポンド法を用いられ、国外向けにはメートル法を用いるという、使い分けをしている。ただし、イギリスのヤード・ポンド法はアメリカのそれとは厳密には同一ではないので注意が必要である。, 日本は、1885年（明治18年）にメートル条約に加入している。1889年（明治22年）にメートル原器の交付を受け、1891年（明治24年）に施行された度量衡法で尺貫法と併用する形でメートル法が導入された。それに伴い、新たに基本単位の漢字を当てたり（※例1）、補助単位の漢字を創作して（※例2）、メートル法がいち早く普及するように努めた。以下に挙げるのはそういった単位である。, 1900年11月10日、東京帝国大学運動会で、初めてヤード制をあらためてメートル制を採用した[13]。 = 36 inches (in.)
