Centimeter (cm)
Definition: A centimeter (cm) is one-hundredth of a meter, making it useful for measuring smaller objects. It provides a convenient unit for everyday applications like measuring body height, book dimensions, and clothing sizes.
History: The centimeter was introduced alongside the metric system to replace inconsistent length units like inches and spans. It became widely accepted due to its ease of use in smaller measurements.
Current Use: Centimeters are used extensively in education, construction, and tailoring. It is the standard unit for rulers and commonly appears in scientific research, engineering, and daily measurements like furniture dimensions.
Nanometer (nm)
Definition: A nanometer (nm) is one-billionth of a meter. It is commonly used in nanotechnology, semiconductor design, and physics to measure atomic-scale structures and wavelengths of light.
History: The nanometer gained importance in the 20th century as scientists developed electron microscopes and advanced microfabrication techniques. It became critical for measuring molecules and tiny electronic components.
Current Use: Nanometers are used in physics, materials science, and chip manufacturing. They help define the scale of microprocessors, DNA strands, and wavelengths in ultraviolet and X-ray light applications.
