noun
scale; vernier caliper
Refers to a measuring instrument, especially a vernier caliper, used for precise length measurements. Not to be confused with 'scale' as in size or musical scale.
スケールで部品の厚さを測る。
Measure the thickness of the part with a vernier caliper.
The same katakana word can also mean 'scale' in the sense of size, range, or musical scale, but this word is specifically for the measuring instrument.
Borrowed from English 'scale', used in Japanese primarily for a vernier caliper or similar measuring tool.
