Ton (Assay) (Us)
The ton (assay) (US), symbolized as AT (US), is a unit of weight used primarily in the assay and precious metals industry, equivalent to 31.1034768 grams.
History/Origin
The assay ton originated in the United States as a standardized measure for precious metal content in assays, aligning with the metric system but retaining the traditional 'ton' terminology for industry consistency.
Current Use
Today, the assay ton (AT US) is used mainly in the precious metals industry for assay purposes, especially in the context of gold and silver purity measurements, and is part of weight and mass conversions within the 'Common Converters' category.
Earth's Mass
Earth's mass (M_earth) is a unit of mass representing the mass of the Earth, approximately 5.972 × 10^24 kilograms.
History/Origin
The concept of Earth's mass as a unit originated from scientific measurements of Earth's size and gravitational influence, becoming a standard reference in geophysics and astronomy.
Current Use
M_earth is used in scientific contexts to express planetary and astronomical masses, and in some cases, to compare the mass of other celestial bodies relative to Earth.
