About these units
Ounce (oz)
The ounce is a unit equal to 1/16 of a pound, or approximately 28.3495 grams, with roots in ancient Roman "uncia"—one-twelfth of a pound. The ounce is used for measuring small masses in cooking, postal services, gemstones (troy ounces), and various consumer goods. Despite not being part of the metric system, the ounce remains a staple in US everyday life, from food packaging to hardware components. Its small size gives it a practical niche where grams might feel too unfamiliar for some audiences. Multiple ounce variants exist historically—avoirdupois, troy, apothecary—but the avoirdupois ounce is now the standard in general commerce. Its endurance reflects the cultural weight of imperial units and the long history of Western measurement systems.
Metric Ton (t)
The metric ton, or tonne, equals 1,000 kilograms and is used for measuring large masses such as vehicles, industrial shipments, agricultural yields, waste disposal, and construction materials. Its convenient decimal relationship with kilograms makes it easy to use in logistics, industry, and environmental studies. Many countries express carbon emissions in tonnes of CO₂, linking the unit directly to global sustainability efforts. The metric ton contrasts with the US short ton and UK long ton—its exact definition prevents ambiguity in international trade. Its adoption worldwide demonstrates the advantages of standardized mass units in a global economy.
