Current Uses: Light-years are essential for describing distances between stars, galaxies, and other celestial objects in the universe. They provide a convenient scale for measuring vast astronomical distances.

Where to Use: Light-years are employed in astronomical research, cosmology, and science education. They help scientists and astronomers understand the scale and structure of the universe.

Hand (hand):

Definition: The hand is a unit of length traditionally used to measure the height of horses, livestock, and other animals. It represents four inches or one-tenth of a yard.

History/Origin: The hand has ancient origins, with different cultures defining it based on the size of a human hand or the width of a palm. It was commonly used in agriculture and equestrian activities.
