About these units
Carat (car, ct)
The carat, equal to 200 milligrams, is the standard unit for measuring gemstones and pearls. Its origins trace to the seeds of the carob tree, which were historically thought to have remarkably uniform mass, making them convenient reference weights for early traders. In the modern gem trade, carats measure both weight and (informally) influence perceived value—though size and quality factors such as clarity and color also play major roles. High-precision digital scales capable of reading to 0.001 carat are common in gemology. The carat's persistence shows how specialized units evolve to meet the needs of niche industries. Though small, its economic impact is enormous due to the value of gemstones.
Earth's Mass (M⊕)
Earth's mass is approximately 5.972 × 10²⁴ kilograms, a fundamental parameter in planetary science and orbital mechanics. It governs Earth's gravitational interaction with the Moon, Sun, and artificial satellites and shapes geological processes such as plate tectonics and atmospheric retention. Planetary scientists use Earth masses to compare exoplanets, enabling quick insights into habitability, composition, and gravitational characteristics.
