测量仪器
A micrometer is a precision measuring tool that uses a calibrated screw to measure very small lengths with high accuracy. It matters because many manufacturing and scientific applications require precise measurements that other rulers or measuring devices cannot provide.

千分尺，中國大陸稱為千分尺(中国大陆的初中课本称其螺旋测微器或千分尺)、台灣稱為螺旋測微器、測微器、分厘卡，一种测量工具，用于精密测量小尺度的长度。 从原理上，螺旋测微器可分为机械式千分尺和电子千分尺两类。机械式千分尺是依据螺旋放大的原理制成的。
