## Description

Millimeter Pro is a powerful and precise screen ruler Chrome extension that transforms your device's full screen into a versatile measuring tool. It allows users to measure length, area, angles, and thread per inch (TPI) with high accuracy comparable to physical rulers or tape measures.

This extension supports calibration using common objects like coins or credit cards, ensuring precise measurements across all devices. Users can measure in metric and imperial units with support for inch fractions. Additional features include vertical rulers for 2D measurement, area calculation, ratio determination, angle measurement with a protractor, circular object measurements, and a spirit level for incline checking. Its clean, ad-free interface enhances usability, and options like night mode and a fine grid improve visualization and power saving.

Millimeter Pro is ideal for professionals and hobbyists needing to measure small objects such as jewelry, screws, knitting patterns, and more, all directly on their device screen. It supports multiple languages including English, German, Russian, Japanese, and French.
