An online ruler (cm/mm) is a digital tool or website that allows you to measure distances, lengths, or objects using centimeters (cm) or millimeters (mm) through your internet browser. It provides a virtual ruler on your screen, which you can use to accurately measure various items or lengths without the need for a physical ruler or measuring tape. Online rulers are particularly helpful when you don't have access to traditional measuring tools or are working in a digital environment.

Here's how you can use an online ruler (cm/mm):

Align the digital ruler with the object or length you wish to measure, and read the measurement value displayed on the screen.
