バーニヤ
バーニヤ is a direct loanword from English 'vernier', often used in the same technical contexts. 遊尺 is the native Japanese term, more common in formal or traditional engineering documentation.

Compound of 遊 (play, idle) and 尺 (measure, scale). The term likely derives from the idea of a 'sliding' or 'moving' scale that 'plays' along the main scale. The exact historical derivation is uncertain.
