About Feet
A foot (ft) is equal to 12 inches or 30.48 centimeters, originally based on the length of a human foot. It remains widely used in the United States and some other countries for measuring height, room dimensions, and distances. For reference, a standard door is about 6.5-7 feet tall, ceiling height in homes is typically 8-9 feet, and a basketball hoop stands 10 feet high. The foot is also used in aviation (altitude) and real estate (square footage).
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.
