1 ounce (oz) equals exactly 2.7902e-05 UK long tons (L/T). Use the formula: oz × 2.7902e-05 = L/T.
To convert ounces to UK long tons, multiply your value in ounces by 2.7902e-05. For example, 5 oz × 2.7902e-05 = 0.00013951 L/T.
100 ounces = 0.00279018 UK long tons. Calculation: 100 × 2.7902e-05 = 0.00279018.
To convert UK long tons back to ounces, divide by 2.7902e-05 (or multiply by 35840.0325). Example: 10 L/T ÷ 2.7902e-05 = 358400.3245 oz.
Yes. This converter uses the internationally recognised exact conversion factor: 1 oz = 2.7902e-05 L/T. All calculations are performed in your browser with no rounding until display.
10 ounces = 0.00027902 UK long tons. Simply multiply by 2.7902e-05.
Converting ounces to UK long tons is commonly needed for freight logistics, commodity trading, construction material procurement, and agricultural reporting where one system uses oz and another uses L/T.
The avoirdupois ounce (oz) equals exactly 28.349523125 grams or 1/16 of an avoirdupois pound. It is widely used in the US and UK for food portions, product packaging, and everyday measurements. Note that the troy ounce (31.1035 g), used for precious metals like gold and silver, is a different and heavier unit than the avoirdupois ounce.
The UK long ton (symbol L/T, also "imperial ton" or "gross ton") equals 2,240 avoirdupois pounds or 1,016.0469088 kilograms. Used in Britain for coal and shipping, it is slightly larger than both the US short ton (2,000 lb) and the metric ton (1,000 kg). Britain adopted metric units in 1965 and the long ton is no longer used in new UK trade contracts, though it appears in historical records.
The word "ounce" derives from Latin uncia (a twelfth), originally 1/12 of the Roman pound. The avoirdupois ounce developed in medieval England specifically for the wool trade, creating a 16-ounce pound distinct from the Troy 12-ounce pound. The British Imperial system codified the ounce in 1824. The modern exact definition (28.349523125 g) was set by the 1959 International Yard and Pound Agreement.
Interesting fact: A troy ounce (31.1 g) used for gold is heavier than an avoirdupois ounce (28.35 g) used for food — so an "ounce" of gold contains more metal than an "ounce" of flour. A standard large hen's egg weighs approximately 56–63 grams (about 2 oz).
The long ton traces to medieval England, where a "wine tun" was a large barrel of ~252 gallons. A standard ship's cargo unit ("ton burden") evolved into a 2,240-pound standard because 2,240 lb = 20 hundredweight (each of 112 lb) — convenient for counting by the hundredweight. The Coal Industry Act 1831 formalised the long ton for coal. British Overseas Territories and some US steel industry sectors still use it.
Interesting fact: HMS Victory, Nelson's flagship at Trafalgar (1805), was rated at 2,162 long tons displacement. Modern international shipping uses metric tons (deadweight tonnage), but engineers working with pre-1965 British specifications regularly need long ton conversions.
