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.

Short Ton

The short ton (symbol tn or t) is a unit of mass primarily used in the United States. It is equal to 2,000 pounds or approximately 907.1847 kilograms. The short ton is part of the U.S. customary system and is smaller than both the long ton (used in the UK) and the metric ton.

Origin:

The short ton originated in the U.S. as a way to standardize weight measurements, particularly for bulk commodities like coal and steel. It is called "short" to distinguish it from the long ton (also known as the imperial ton), which is used in the UK and equals 2,240 pounds. The short ton became widely used in the United States during the 19th century as part of the U.S. customary system of measurements.
