What does 計器[けいき] mean?

The word 計器[けいき] refers to "measuring instrument" or "measuring device" in Japanese. It is composed of two kanji: 計 (to measure, to calculate) and 器 (utensil, instrument). Together, they form a term used to describe devices that assess physical quantities, such as pressure, temperature, or speed.

You will find 計器 in technical environments such as laboratories, industries, and even in airplanes, where panels full of gauges are called 計器盤[けいきばん]. Although it is a more formal term, it is essential for those who work in engineering, maintenance, or sciences.

How to memorize 計器 [けいき]?

An effective way to memorize this word is to break it down into parts. The kanji 計 appears in other terms like 計算[けいさん] (calculation) and 時計[とけい] (clock), while 器 is used in words like 食器[しょっき] (kitchen utensils). Associating 計器 with "instrument that measures" helps to avoid confusing it with similar terms.

Another tip is to practice with real sentences, such as "この計器は正確ですか？" (Is this instrument accurate?). Repeating the term in practical contexts consolidates learning. If you use flashcards, including an image of a gauge alongside the word can reinforce visual memory.

In Japan, 計器 is a common term in professional settings, but rare in informal conversations. Its presence in technical manuals and industrial training is strong, reflecting the importance of precision in Japanese culture. Companies like Mitsubishi and Hitachi frequently use this term in their documentation.
