lh = nm × 9.265669311e-22
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 Light Hours
A light hour (lh) is the distance light travels in one hour through a vacuum, approximately 1.08 billion kilometers. Jupiter is about 0.72 light hours from the Sun, while Saturn orbits at roughly 1.3 light hours. This unit is useful for expressing distances to the outer planets and understanding communication delays with spacecraft. A radio signal to a probe near Jupiter takes about 43 minutes to arrive, representing the vast scales even within our solar system. Pluto at its farthest reaches about 5.5 light hours from the Sun.
