About Light Seconds

A light second (ls) is the distance light travels in one second through a vacuum, exactly 299,792,458 meters. This represents one of the fundamental constants in physics - the speed of light. For perspective, light takes about 1.3 seconds to travel from Earth to the Moon, and 8.3 minutes (500 light seconds) to reach us from the Sun. This unit is crucial in astronomy, telecommunications (satellite delays), and physics experiments, helping us understand the finite speed of light and its implications for communication and observation.

About Thou

A thou (also called mil) is one thousandth of an inch, equal to 0.0254 millimeters or 25.4 micrometers. This unit is commonly used in engineering and manufacturing in countries that use imperial measurements, particularly for specifying tolerances, wire gauges, and thin material thicknesses. For example, a standard plastic bag might be 1-2 thou thick, a sheet of paper is about 4 thou, and precision machined parts often have tolerances measured in thou. Electronic circuit board copper traces are typically 1.4 thou thick.
