When an object is shorter than a centimeter?

Answer 1

When an object is shorter than a centimeter, it is typically considered very small, often categorized as a millimeter or even smaller. Objects of this size can include tiny components like grains of sand, small insects, or fine electronic parts. Measurements at this scale often require precision tools like calipers or microscopes for accurate assessment. Such small dimensions can be significant in fields like engineering, Biology, and materials science.
