About US ton (short ton) (ton)
The US ton, also called the short ton, is a unit of mass equal to 2,000 pounds (approximately 907 kg). It is the standard large-mass unit in the United States for bulk materials such as coal, gravel, recycled metals, and agricultural commodities. The short ton is roughly 10% lighter than the metric tonne (1,000 kg) and about 12% lighter than the imperial long ton (1,016 kg). In practice, "ton" in American English almost always means the short ton. Cargo weight, construction materials, and HVAC capacity (where "ton" refers to cooling capacity derived from melting a short ton of ice per day) all use the short ton.
A pickup truck typically has a payload capacity of 0.5–1 short ton. A cord of firewood weighs roughly 2–2.5 short tons.
About Ounce (oz)
The avoirdupois ounce (oz) is 1/16 of a pound, equal to approximately 28.35 grams. It is the standard unit for food portions, postal weights, and everyday goods in the United States and, to a declining degree, the United Kingdom. The ounce should not be confused with the fluid ounce (a volume unit) or the troy ounce (31.1 g, used for precious metals). In cooking, most American recipes use ounces for dry ingredients; UK recipes have largely switched to grams. Postal systems in the US still price letters by the ounce.
A standard letter envelope weighs about 0.2 oz. A slice of cheese is roughly 1 oz. A baseball weighs 5–5.25 oz.
Etymology: From the Latin "uncia" (one twelfth), the twelfth of a Roman pound. The avoirdupois ounce (1/16 lb) diverged from the troy ounce (used for metals) in medieval England.
US ton (short ton) – Frequently Asked Questions
How many pounds are in a US (short) ton?
One US short ton equals exactly 2,000 pounds (approximately 907 kg). To convert short tons to kilograms, multiply by 907.185. To convert to metric tonnes, multiply by 0.907.
What does "ton" mean in air conditioning (HVAC)?
In HVAC, a "ton of refrigeration" is a unit of cooling power equal to the heat absorbed by melting one short ton (2,000 lbs) of ice in 24 hours — approximately 3.517 kilowatts or 12,000 BTU/hour. A 3-ton AC unit has 3 × 12,000 = 36,000 BTU/h of cooling capacity. This has nothing to do with the weight of the equipment.
How many tons of food does an average person eat in a lifetime?
An average person in a developed country eats roughly 2–2.5 lbs of food per day (about 1 short ton per year). Over a 75-year lifespan, that is approximately 75 short tons (68 metric tonnes) of food — enough to fill about three standard shipping containers. Broken down: roughly 8 tonnes of fruit and vegetables, 5 tonnes of meat, 6 tonnes of grain products, 8 tonnes of dairy, and the rest in fats, sugars, and beverages. The water required to produce that food is about 50,000 tonnes — 700 times the food weight itself.
Which industries in the US still use short tons?
Short tons remain standard in US coal mining and electricity generation, steel and ferrous scrap recycling, agricultural commodities (grain, fertiliser), and construction materials (gravel, asphalt). International trade documentation typically requires conversion to metric tonnes for global contracts.
What weighs exactly one short ton that you might encounter in daily life?
A Honda Civic (2024 base model) has a curb weight of almost exactly 2,000 lbs — one short ton. A standard pallet of bottled water (84 cases of 24 × 500 mL bottles) weighs about 2,000 lbs. A cubic yard of dry sand weighs roughly one short ton. A grand piano ranges from 700 to 1,200 lbs, so you need about two of them. A typical adult horse weighs 900–1,100 lbs, so two average horses together are close to one short ton.
Ounce – Frequently Asked Questions
How many ounces are in a pound?
There are exactly 16 ounces (oz) in one avoirdupois pound (lb). This is the standard US and UK system for everyday weights. Note that the troy pound (used for precious metals) contains 12 troy ounces — a different and less common system.
What is the difference between an ounce and a fluid ounce?
An ounce (oz) is a unit of weight (mass); a fluid ounce (fl oz) is a unit of volume. For water at room temperature they happen to be close (1 fl oz of water ≈ 1.04 oz by weight), but for other liquids (oil, honey, milk) the values diverge. Recipes that say "8 oz of flour" mean weight; "8 fl oz of milk" mean volume.
What is a troy ounce?
A troy ounce is 31.1035 grams — heavier than the avoirdupois ounce (28.35 g). Troy ounces are used exclusively for precious metals (gold, silver, platinum, palladium). When gold prices are quoted per ounce, they always mean troy ounces.
Why do US recipes use ounces for solids when the rest of the world uses grams?
American home cooking developed around volume measures (cups, tablespoons) and weight in ounces because kitchen scales were uncommon in US households until recently. The rest of the world adopted metric kitchen scales as part of broader metrication. Ounces persist in US recipes partly because American measuring cup sets are ubiquitous and cheap, and partly because US food packaging lists serving sizes in ounces. Professional American bakeries increasingly use grams for precision, but consumer recipes lag behind because publishers fear alienating home cooks who do not own a scale.
Does the UK still use ounces?
Officially the UK moved to metric in the 1970s–1990s, but ounces persist in informal use, especially in older recipes, market stalls, and body weight conversations. UK supermarkets label food in grams and kilograms; loose goods at markets are increasingly metric. The ounce is no longer a legal unit of trade in the UK for pre-packaged goods.
