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.

About Picometers

A picometer (pm) is one trillionth of a meter (10⁻¹² m), making it 1,000 times larger than a femtometer but still unimaginably small. This unit is crucial in atomic and molecular physics, as it represents the scale of atomic radii and chemical bonds. For example, a hydrogen atom has a radius of about 53 picometers, and the length of a typical chemical bond ranges from 100 to 200 picometers. X-ray wavelengths also fall within this range.
