Symmetric Metric Ruler Image - Free Download for Educational & Design Use #3855911 (License: Personal Use)

This black-and-white ruler features a symmetrical scale ranging from -50 to +50 units, with major tick marks every 10 units and minor ticks for single-unit precision. The clean, minimalist design ensures clarity for educational diagrams, engineering schematics, or digital interface mockups requiring a neutral measurement reference.

Commonly used in mathematics education (e.g., number lines, vectors), graphic design (layout guides), and technical documentation where bidirectional measurement or origin-centered scaling is needed. Matches user intent for free, high-contrast clipart or SVG assets.
