About Meters
The meter (m) is the fundamental unit of length in the International System of Units (SI) and is used worldwide. Originally defined as one ten-millionth of the distance from the Earth's equator to the North Pole, it's now precisely defined as the distance light travels in a vacuum in 1/299,792,458 of a second. A meter is roughly the height of a kitchen counter, the width of a large door, or one large step for an adult. Most countries use meters for measuring room sizes, building heights, and short distances.
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.
