pascal
パスカル
解説 Definition
pascal は圧力の単位「パスカル」という意味です。日本語のカタカナ語とほぼ同じ意味で使われ、1 pascal のように数値とともに用いられます。
A pascal is the SI unit of pressure, equal to one newton of force applied over an area of one square metre. It is commonly used with a number or in larger units such as kilopascals.
覚え方のコツ Memory Tip
pascal は圧力のSI単位で、記号は Pa。科学者 Blaise Pascal の姓から名づけられました。「one pascal」「measured in pascals」のように数値や in と結びつけます。1 Pa は非常に小さい圧力なので、実用では kilopascal も一緒に覚えると定着します。
Connect pascal with pressure and its symbol, Pa. The unit was named after the scientist Blaise Pascal, so the capitalized surname Pascal and the lowercase unit pascal have different functions. Learn it in practical patterns such as one pascal, measured in pascals, and pressure in pascals. Because one pascal is a very small amount of pressure, kilopascal is often more useful in everyday measurements. That connection helps place the word in scientific contexts rather than treating it as only a katakana term.
例文
One pascal is a very small unit of pressure.
1パスカルはとても小さな圧力の単位です。
The sensor can detect a change of one pascal.
そのセンサーは1パスカルの変化を検出できます。
The pressure was recorded in pascal units.
圧力はパスカル単位で記録されました。

pascal の語源・成り立ち Etymology
pascal は圧力の単位名で、科学者 Blaise Pascal の姓にちなみます。Pascal という名自体は後期ラテン語 paschalis「復活祭の・過越祭の」に由来し、さらにヘブライ語 pesach にさかのぼるため、「復活祭に関わる名」が人名となり単位名になった形です。関連語は Paschal, pasch。
The pressure unit was named in honor of the French mathematician and physicist Blaise Pascal. His surname ultimately derives from Late Latin paschalis, meaning “of Easter or Passover,” which is related through earlier forms to Hebrew pesach, “Passover.” Thus, a word originally associated with a religious festival became a personal name and surname, and that surname was later adopted as the name of an SI unit.
