About Meters
The meter (m) is the fundamental unit of length in the International System of Units (SI) and is used worldwide. Originally defined as one ten-millionth of the distance from the Earth's equator to the North Pole, it's now precisely defined as the distance light travels in a vacuum in 1/299,792,458 of a second. A meter is roughly the height of a kitchen counter, the width of a large door, or one large step for an adult. Most countries use meters for measuring room sizes, building heights, and short distances.
About Nanometers
A nanometer (nm) is one billionth of a meter (10⁻⁹ m), roughly the width of 3-4 atoms placed side by side. This scale is where nanotechnology operates and is visible light wavelengths are measured. Visible light ranges from about 400 nm (violet) to 700 nm (red). DNA molecules are about 2.5 nm wide, and modern computer processors have transistors as small as 3-5 nm. A human hair is approximately 80,000-100,000 nanometers thick, making one nanometer incredibly tiny by human standards.
