• ✓1 oz = 28.35 g exactly (avoirdupois); 1 troy oz = 31.10 g.
• ✓16 oz = 1 lb in the avoirdupois system used for food.
• ✓When converting a US recipe, 1 oz ≈ 2 tablespoons of a liquid ingredient.

• ✗Confusing mass ounces (28.35 g) with fluid ounces (volume).
• ✗Using avoirdupois ounces (28.35 g) for precious-metal pricing — gold is in troy ounces (31.10 g).
• ✗Multiplying lb × 16 and calling the result oz — correct only for weight, not volume.

What is the Ounce?

The ounce equals exactly 28.349523125 grams or 1/16 of a pound. The word derives from the Latin 'uncia,' meaning one twelfth (the original Roman ounce was 1/12 of a Roman pound). The modern avoirdupois ounce, used for everyday weights in the United States and the United Kingdom, replaced the older Tower and Troy systems. It is the standard unit for American kitchen recipes (where 'ounce' refers to weight, distinct from the fluid ounce of volume), postal rates, package sizes (a 12-oz can of soda), and boxing-glove weights. Precious metals like gold and silver use the troy ounce (31.103 g), about 10% heavier than the avoirdupois ounce. The ounce relates to the pound (16 oz = 1 lb), the gram (1 oz ≈ 28.35 g), and the grain (1 oz = 437.5 grains).

What is the Metric Ton?

The metric ton (or tonne) equals exactly 1,000 kilograms and is the international standard for shipping, agriculture, construction, and industrial weight. Adopted as part of the SI system, the metric ton is used worldwide for bulk commodities (grain harvests measured in tons per hectare), vehicle and shipping container masses, freight rates, and CO₂ emissions accounting. A standard 20-foot shipping container has a maximum gross weight of about 24 metric tons. The metric ton is distinct from the US short ton (907.185 kg) and the UK long ton (1,016.047 kg). The unit's spelling differs by country — 'tonne' in British and international usage, 'metric ton' in American — but the abbreviation 't' is universal. It relates to the kilogram (1,000 kg = 1 t) and the megagram (1 Mg = 1 t).

• Agricultural yield (grain, sugar, coffee)
• Steel, cement and industrial production
