About these units
Stone (st)
The stone equals 14 pounds, or approximately 6.35029 kilograms, and is commonly used in the United Kingdom and Ireland for expressing human body weight. It has deep traditional roots, originating from stones used as counterweights in early commerce. Although largely replaced by metric units in most applications, the stone remains emotionally and culturally significant for personal weight expression in the UK. Many people find it more intuitive and relatable than kilograms due to long-standing social habits. The stone's endurance highlights how measurement systems reflect cultural identity as much as mathematical convenience. It is one of the few units still commonly used in conversation but not in scientific or industrial contexts.
Gigagram (Gg)
A gigagram equals 1,000 megagrams, or one million kilograms. It is used in industrial-scale output, national food production statistics, and environmental assessments, such as annual emissions of pollutants. Governments and researchers analyzing natural resource consumption, waste management, or ecological footprints frequently rely on gigagram-level reporting. The Gg sits at the intersection of human-scale systems and planetary-scale studies, offering clarity for large quantities.
