What is a Dram and a Ton (metric)?
The dram (or drachm) can refer to several units. In the context of common weight conversion (Avoirdupois system), it is a unit of mass equal to 1/16 of an ounce or 1/256 of a pound. This Avoirdupois dram is approximately 1.7718 grams.
The metric ton (or tonne) is a unit of mass equal to 1,000 kilograms (kg). It is part of the International System of Units (SI) although not technically an SI unit itself, it is accepted for use with SI. It is equivalent to approximately 2,204.6 pounds.
Note: The Dram is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Ton (metric) belongs to the imperial/US customary system.
History of the Dram and Ton (metric)
The term originates from the Greek drachma coin. It became a unit in multiple historical weight systems (Avoirdupois, Apothecaries', Troy). The Avoirdupois dram was used for general commodities.
The term "tonne" derives from the "tun", an old English unit of volume for large casks. The metric tonne was defined as 1,000 kilograms to provide a larger metric unit for trade and industry, aligning with the decimal nature of the SI system.
Common Uses for drams and tons
Explore the typical applications for both Dram (imperial/US) and Ton (metric) (imperial/US) to understand their common contexts.
Common Uses for drams
- Historical Measurement: Found in older texts and recipes.
- Ammunition Reloading: Powder charges are sometimes measured in dram equivalents (though grains are more common).
- Note: The fluid dram (fl dr) is a unit of volume in the Apothecaries' system, distinct from the Avoirdupois dram mass unit.
Common Uses for tons
- Transportation: Measuring the mass of vehicles like cars, trucks, and heavy machinery.
- Shipping & Logistics: Quantifying large amounts of bulk cargo in shipping (e.g., coal, grain, ore).
- Agriculture: Expressing crop yields and large-scale agricultural production.
- Heavy Industry: Standard unit for production outputs in steel manufacturing, mining, and construction.
- Waste Management: Used for calculating municipal solid waste volumes and recycling quantities.
