Ounce

The ounce (oz) is a unit of mass or weight used in both the imperial system and the U.S. customary system. It is defined as 1/16 of a pound or approximately 28.3495 grams. The ounce is commonly used to measure small quantities of food, beverages, and precious metals.

Origin:

The ounce traces its origins to ancient Roman times, where it was based on the uncia, which was 1/12 of a Roman pound (libra). The term "ounce" comes from the Latin "uncia", meaning one-twelfth. In medieval Europe, the ounce evolved as a standardized unit of weight, especially in trade. By the 14th century, the Avoirdupois ounce became the standard for most goods in England, which is equivalent to about 28.35 grams. This measurement was later adopted in the United States and other countries using the imperial system.

Milligram

The milligram (mg) is a unit of mass in the metric system, equal to one-thousandth of a gram (0.001 g) or one-millionth of a kilogram (0.000001 kg). Since the gram and kilogram are defined using the Planck constant (h) in the International System of Units (SI), the milligram is indirectly tied to this same constant, ensuring precision and consistency.

Origin:

The milligram originated as a derived unit of mass within the metric system, introduced during the French Revolution in the late 18th century. As part of the decimal-based metric system, it was designed to provide a smaller and more convenient unit for measuring very light objects, especially in scientific and medical contexts. It is defined in relation to the gram, which was originally based on the mass of one cubic centimeter of pure water at 4°C.
