馬力をキロワットに換算するには？
仏馬力の数に 0.7355 を掛けます。日本とドイツで PS、フランスで ch、スペインとイタリアで CV と書かれるのがこの馬力です。米国の資料に載る出力は、ほぼ必ずもう一方の馬力です。
kW = PS × 0.7355PS = kW ÷ 0.7355
この二つの単位が使われる場所
仏馬力は正確に 735.49875 ワット、すなわち 75 重量キログラムを毎秒 1 メートル持ち上げる仕事率で、機械馬力より 1.4 パーセント小さい値です。 キロワットは欧州連合における原動機出力の法定単位であり、馬力はその横に併記できるだけで、単独で示すことは認められていません。 切りのよい数は、すべて馬力の側に落ちます。90、110、150、200 PS はそれぞれ 66、81、110、147 キロワット。だから車検証の出力は、いつも中途半端な数に見えるのです。 電気自動車はこれを逆にします。諸元は 150 kW や 210 kW とキロワットで公表され、今度は馬力のほうが 204 PS、286 PS と半端になります。

仏馬力は定義により毎秒 75 キログラム重メートル、すなわち厳密に 735.49875 W です。国際単位系には属しませんが、法定値であるキロワットを併記することを条件に、いくつかのヨーロッパ諸国では商業表示に引き続き認められています。 算出方法と出典.
よくある質問
150 PS が 150 hp にならないのはなぜですか？
日常語では同じ「馬力」でも、単位が二つあるからです。150 PS は 110.3 kW、150 hp は 111.9 kW です。互いに換算すると 150 PS は 148 hp にあたります。1.4 % の差は定義に由来し、片や毎秒 75 kgf·m、片や毎秒 550 ft·lbf です。
馬力と課税出力はどう違いますか？
まったく別物です。馬力は機械的な仕事率を測ります。課税出力は行政が出力や場合によっては CO2 排出量から算出する数値で、税額を決めるためだけのものです。150 PS の車が課税上は 8 と記されることもあります。
正確な係数はいくつですか？
0.73549875 で、当サイトの表では 0.7355 に丸めています。逆向きにはキロワットに 1.35962 を掛けます。日常の会話では 0.74 で足り、150 PS までなら誤差は 1 馬力を超えません。
バイクも馬力で表しますか？
はい、ただし桁が変わります。125 cc のスクーターはおよそ 15 馬力すなわち 11 kW、ツアラーは 100 PS で 73.5 kW、レース由来のスーパースポーツは 200 PS を超えます。ヨーロッパの A2 免許は 35 kW が上限で、47.6 PS にあたります。
PS、CV、pk、hk は同じ馬力ですか？
はい、いずれも 735.5 W です。仏馬力はドイツとオーストリアで PS、フランスで ch、スペインとイタリアとポルトガルで CV、オランダで pk、北欧で hk、中欧で ks、日本では 馬力 と書かれます。ですから PS で示された日本や韓国の諸元は、ドイツの諸元とそのまま比べられます。別物なのは英米の hp だけで、こちらは 745.7 W です。
