Translation guide
A micrometer is a precision measuring instrument used to measure small distances or thicknesses, often in engineering and machining. In Japanese, the term is usually expressed with the loanword マイクロメーター or the native term マイクロメータ. The unit of length (one millionth of a meter) is also called マイクロメートル.
The precision tool used to measure small dimensions, such as the thickness of a sheet of metal or the diameter of a wire.
The most common term for the measuring instrument. It is a direct loanword from English and widely understood in technical contexts.
マイクロメーターで部品の厚さを測ります。
I measure the thickness of the part with a micrometer.
A slightly shortened form, also common. It is essentially the same as マイクロメーター but may be preferred in some technical documents.
このマイクロメータは精度が高い。
This micrometer has high precision.
A native Japanese term for micrometer, literally 'measure-micro-meter'. It is rarely used in modern technical contexts, where the loanword is preferred.
測微計を用いて精密測定を行う。
Perform precision measurement using a micrometer.
The unit of length equal to one millionth of a meter (µm).
The standard term for the unit of length. It is used in scientific and engineering contexts.
この繊維の直径は約10マイクロメートルです。
The diameter of this fiber is about 10 micrometers.
An older term for micrometer, still used in some industries. It is equivalent to マイクロメートル but may be considered outdated in formal scientific writing.
マイクロメーター refers to the measuring instrument, while マイクロメートル refers to the unit of length. Confusing them can lead to misunderstandings in technical contexts.
マイクロメーターで測った長さは25マイクロメートルだった。
The length measured with the micrometer was 25 micrometers.
フィルターの目開きは5ミクロンです。
The filter's mesh size is 5 microns.
