A digital ruler is an electronic measuring device that provides precise measurements of length, width, or depth. Unlike traditional rulers or tape measures, digital rulers use sensors and electronic displays (often LCD or LED) to show measurements accurately, usually in both metric (mm/cm) and imperial (inches) units. They are widely used in engineering, design, woodworking, tailoring, and education where precision is critical.
