Meter (m)
Definition: The meter (m) is the base unit of length in the International System of Units (SI), defined by the speed of light in a vacuum. One meter is the distance light travels in 1/299,792,458 of a second.
History: The meter was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole. It has since been redefined multiple times, most recently in 1983 using the speed of light.
Current Use: The meter is universally used in science, engineering, and daily life for measuring objects, distances, and heights. It is the foundation of the metric system and adopted by nearly every country worldwide.
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.
