Tips

Use these in everyday conversions
  • 1 lb ≈ 453.6 g ≈ ½ kg. For mental conversion: kg = lb / 2.2.
  • 1 lb = 16 oz exactly. American recipes often mix pounds and ounces.
  • UK shop labels often show kg and lb together; US labels are pounds only.

Common Mistakes

Avoid these
  • Using 2 instead of 2.205 when converting lb to kg — a 10% error on airline luggage.
  • Confusing mass pounds (lb) with pound-force (lbf) in engineering.
  • Assuming a British and American pound are different — they are identical (0.45359237 kg).

About Pound and Metric Ton

What is the Pound?

The pound equals exactly 0.45359237 kilograms under the 1959 international yard and pound agreement. The unit's name comes from the Latin 'libra pondo' (a pound by weight), and the abbreviation 'lb' derives from 'libra.' The pound has been the everyday weight unit in English-speaking countries for over a thousand years, with regional variations until 20th-century standardization. Today it remains the primary weight unit in the United States for body weight (a person is '170 lb' rather than 77 kg), groceries, and shipping; in the United Kingdom it persists alongside kilograms, especially for personal weight ('11 stone 4' = 158 lb). The pound relates to the ounce (16 oz = 1 lb), the stone (14 lb = 1 stone), the kilogram (1 lb ≈ 0.454 kg), and the US ton (2,000 lb = 1 ton). The international 'avoirdupois' pound is the common standard, distinct from the troy pound used for precious metals.

  • Human body weight in the US and UK
  • Grocery and retail food pricing in the US
  • Boxing and wrestling weight divisions
Real-world examples

An average adult is 130–200 lb. US airline luggage allowance is usually 50 lb (22.7 kg). A gallon of milk weighs about 8.6 lb.

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).

  • International shipping and freight
  • Agricultural yield (grain, sugar, coffee)
  • Steel, cement and industrial production
Real-world examples

A mid-size car weighs about 1.5 t. A 20-ft shipping container holds up to 28 t. Global steel output is about 1,900 million tonnes per year.
