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.

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.
