About these units
Gallon (US) (gal (US))
The US gallon is defined as exactly 231 cubic inches, or 3.785411784 liters. It is widely used in American commerce for gasoline, milk, water, and other household liquids. Its historical roots lie in old English wine and ale gallons, whose varying definitions ultimately led to divergent US and UK systems. Today, the US gallon remains deeply embedded in American culture, especially in automotive contexts—fuel economy ratings such as "miles per gallon" (MPG) illustrate its everyday relevance. Despite the global shift toward metric volume units, the US gallon persists due to familiarity and regulatory inertia. It remains an iconic unit, symbolizing uniquely American measurement traditions.
Earth's Volume (V⊕)
The volume of Earth is approximately 1.08321 × 10¹² cubic kilometers, representing the space occupied by the entire planet. This massive number underpins calculations in geology, seismology, planetary science, and orbital mechanics. For example, Earth's volume helps determine average density, which in turn informs scientists about the planet's interior structure—its crust, mantle, and core. The Earth's volume also allows comparison to other planets, moons, and exoplanets, providing insight into their likely composition, habitability, and geological evolution. Measuring the volume of Earth is a triumph of scientific precision, relying on satellite geodesy, mathematical modeling, and centuries of accumulated observation.
