About Ounce (oz)

An imperial unit of mass equal to exactly 1/16 of an avoirdupois pound = 28.349523125 g per NIST SP 811. The avoirdupois ounce is the everyday US small-mass unit for: food portion sizes per FDA 21 CFR 101.9 + USDA Food Patterns (typical protein serving 3 oz cooked meat; 1 oz cheese; 1 oz nuts; 8 oz cup of liquid; lean meat lean 3-4 oz recommended per meal), American cookbook ingredient measurements (1 tablespoon = 0.5 fl oz volume but the 'oz' in 'oz of flour' is mass = 28.35 g), boxing glove weights per Boxing Association rules (typical 8-10 oz pro-boxing; 12-16 oz training-bag), postal rates per USPS (Domestic First-Class up to 13 oz, then Priority Mail rates; international First-Class up to 4 lb in oz increments), and chocolate-bar + nut + cereal-product labeling. Reference values: 1 stick of US butter = 4 oz = 1/2 cup = 8 tablespoons; an Apple iPhone 15 Pro Max ~7.8 oz; a US baseball regulation 5-5¼ oz per MLB rule 3.01. CRITICAL: distinct from troy ounce (~31.103 g, used exclusively for precious metals — 1 troy oz Au differs from 1 avoirdupois oz Au by ~10%, a common confusion when comparing gold quotes to grocery scales). Convert avoirdupois oz to grams by multiplying by 28.349; to troy oz by dividing by 1.097.

About Metric Ton (t)

A metric unit of mass equal to exactly 1,000 kg ≈ 2,204.62 lb. The metric ton — also called 'tonne' in international English (the official BIPM SI Brochure spelling) — is the global commodity unit for bulk shipping per IMO + ICAO, industrial manufacturing per ISO 9001 + ISO 14001 production reporting, agricultural yield (USDA WASDE reports global crop production in million metric tons: 2024 global wheat ~790 Mt, corn 1,200 Mt, soybeans 410 Mt, rice 530 Mt, palm oil 80 Mt; FAO reporting in Mt or kt), steel production (worldsteel.org global crude steel ~1,900 Mt/year, China ~1,020 Mt, India 140 Mt, Japan 87 Mt, USA 80 Mt), and CO₂ emissions reporting per IPCC AR6 + UNFCCC + Carbon Brief / Our World in Data (global anthropogenic 37 Gt CO₂/yr = 37,000 Mt; per-capita US ~16 t/yr, China 8.3 t, EU 6.5 t, India 1.9 t per 2023 data; airliner round-trip NYC-LON 1.6 t CO₂ per passenger). Reference values: a typical 40 ft shipping container max gross 30 t; loaded Class-8 semi-truck 36 t US (80,000 lb GVW); standard passenger car curb weight 1.0-2.5 t; Saturn V rocket fully fueled 2,970 t. Distinct from US short ton (2,000 lb = 907.18 kg) and UK long ton (2,240 lb = 1,016.05 kg).

Understanding Ounces

The Ounce (symbol: oz) is a unit of weight & mass. An imperial unit of mass equal to exactly 1/16 of an avoirdupois pound = 28.349523125 g per NIST SP 811. The avoirdupois ounce is the everyday US small-mass unit for: food portion sizes per FDA 21 CFR 101.9 + USDA Food Patterns (typical protein serving 3 oz cooked meat; 1 oz cheese; 1 oz nuts; 8 oz cup of liquid; lean meat lean 3-4 oz recommended per meal), American cookbook ingredient measurements (1 tablespoon = 0.5 fl oz volume but the 'oz' in 'oz of flour' is mass = 28.35 g), boxing glove weights per Boxing Association rules (typical 8-10 oz pro-boxing; 12-16 oz training-bag), postal rates per USPS (Domestic First-Class up to 13 oz, then Priority Mail rates; international First-Class up to 4 lb in oz increments), and chocolate-bar + nut + cereal-product labeling.
