Gram

The gram (g) is a unit of mass in the metric system, and it is equal to one-thousandth of a kilogram (0.001 kg). Since the kilogram is the SI base unit of mass defined by the Planck constant (h), the gram is indirectly defined by the same constant. This modern definition ensures the gram's precision and stability as part of the International System of Units (SI).

Origin:

The gram was introduced in 1795 during the French Revolution as part of the metric system's creation. Originally, it was defined as the mass of one cubic centimeter of pure water at its maximum density (approximately 4°C). This practical link to water made it a convenient and universal reference. The gram served as a base unit of mass in early metric systems, but in 1889, the kilogram was adopted as the primary standard, making the gram a derived unit equal to one-thousandth of a kilogram.

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.
