History of ton (short)/hour [ton (US)/h] unit

The unit developed from the short ton, a North American measure standardized at 2,000 avoirdupois pounds. The word “ton” derives from the Old English tunne, referring to a large cask, and historically represented different quantities in different regions. As industrial plants adopted continuous handling of coal, grain, minerals, waste, and chemicals, mass-per-time measurements became essential. Engineering practice consequently combined the short ton with the hour, producing ton/hour for material throughput. Today, it remains familiar in the United States and Canada, although SI units like tonnes per hour are preferred internationally.
