What is a kilogram?
A kilogram is metric unit of weight subdivided into 1,000 grams. The base unit of mass in the International System of Units (SI) is a kilogram and not, as is quite often mistaken, the gram.
One liter of water weighs 1kg.
What are Troy Ounces?
Troy ounces are a unit of measurement commonly used in the precious metals industry, particularly for weighing gold, silver, and other precious metals.
One troy ounce is equivalent to approximately 31.1035 grams, which is slightly heavier than a standard avoirdupois ounce. The term "troy" originates from the city of Troyes in France, where this unit of measurement was historically used in the trade of precious metals.
