About Imperial ton (long ton) (ton)
The imperial ton, also called the long ton, is a unit of mass equal to 2,240 pounds (approximately 1,016 kg). It was the standard large-mass unit in the British Empire for bulk goods such as coal, grain, and shipping capacity. The long ton is still used in some UK industries (particularly shipping tonnage and historical contexts) but has largely been replaced by the metric tonne (1,000 kg) for commercial and scientific purposes. The difference between the long ton (1,016 kg), metric tonne (1,000 kg), and US short ton (907 kg) is roughly 10–12%, which matters in trade and engineering calculations.
A double-decker bus weighs about 8 long tons. A coal wagon in Victorian railways held about 10 long tons.
About Gram (g)
The gram (g) is the fundamental practical unit of the metric system for everyday weights, defined as one thousandth of the kilogram — itself the SI base unit of mass. The gram is the standard unit for food ingredients, postal weights, and laboratory measurements. It was historically defined as the mass of one cubic centimeter of water at 4°C, a relationship that still holds approximately. The gram is small enough for precision in cooking and chemistry while being a convenient step between the milligram (pharmaceutical) and kilogram (everyday weight) scales.
A standard paperclip weighs about 1 g. A AA battery weighs roughly 23 g. A slice of bread is about 30 g.
Etymology: From the Late Latin "gramma" and Greek "grámma" (small weight), originally a unit used in apothecary measurement. Adopted by the French metric system in 1795.
Imperial ton (long ton) – Frequently Asked Questions
What was the heaviest single object ever weighed?
The revolving service structure at NASA's Kennedy Space Center Launch Complex 39B weighed approximately 2,423 long tons (2,462 metric tonnes) when it was moved on its rail system. In construction, the Troll A offshore gas platform (North Sea) had a concrete substructure weighing about 656,000 tonnes — the heaviest object ever moved by humanity. For natural objects, the heaviest single organism is the Pando aspen grove in Utah at an estimated 6,000 tonnes, though it is debatable whether a clonal colony counts as one "object."
Is the long ton still used?
The long ton persists in some specialist UK contexts — notably maritime shipping displacement (warship displacement is often quoted in long tons), some historical industrial records, and a few US sectors such as ferrous scrap metal trading. For most purposes, the metric tonne has replaced it in the UK.
How does the long ton compare to the metric tonne?
A long ton is 1,016.05 kg, which is about 1.6% heavier than a metric tonne (1,000 kg). For rough mental conversion, they are close enough that long ton ≈ metric tonne — but in bulk commodity contracts, the 16 kg difference per tonne adds up significantly at large volumes.
Why does the UK use a different ton than the US?
Both derived from the historical English ton of 2,240 lbs (based on 20 hundredweight of 112 lbs each). The US customary system later redefined the hundredweight as 100 lbs, producing a short ton of 2,000 lbs, while the UK retained the 112-lb hundredweight and the 2,240-lb long ton.
What is a deadweight ton?
Deadweight tonnage (DWT) is a shipping measure of how much weight a vessel can carry — cargo, fuel, crew, provisions, and water — expressed in metric tonnes or long tons depending on convention. A Panamax cargo ship typically has a deadweight of 50,000–80,000 metric tonnes. DWT is distinct from displacement tonnage (the weight of water displaced by the ship itself).
Gram – Frequently Asked Questions
How many grams are in an ounce?
One avoirdupois ounce equals exactly 28.3495 grams. For rough mental arithmetic, 28 g per ounce is commonly used. A 100 g weight is approximately 3.5 oz.
What weighs exactly 1 gram?
A standard US dollar bill weighs almost exactly 1 gram (1.0 g). A paperclip is approximately 1 g. A cubic centimeter of water weighs 1 g at 4°C — the original definition of the gram.
What is the difference between a gram and a gramme?
"Gram" and "gramme" refer to the same unit. "Gramme" is the French-derived spelling used in the UK and Commonwealth countries; "gram" is the US and international standard spelling. Both are correct; "gram" is more common in scientific writing and on nutrition labels worldwide.
How many grams of protein should I eat per day?
The general recommendation for sedentary adults is 0.8 g of protein per kilogram of body weight per day. For a 70 kg adult, that is 56 g/day. Athletes and those building muscle are often advised to consume 1.2–2.0 g per kg, or 84–140 g/day for the same 70 kg person.
Why is gold priced per gram but other metals per kilogram?
Gold is dense and extremely valuable relative to its volume — a kilogram of gold is worth tens of thousands of dollars, making grams a more practical transaction unit. Precious metals (gold, silver, platinum) are also traded in troy ounces (31.1 g). Industrial metals like copper or steel are cheap enough that pricing per kilogram or tonne is more practical.
