Ton (assay) (US)
The assay ton (US) equals about 29.167 grams, a mining-assay convenience unit.
Devised so an assay sample's metal in milligrams reads as troy ounces per short ton.
Ore assaying and metallurgy.
Adopted in assay laboratories to simplify ore-grade calculation.
Pound
The pound (lb) is a unit of mass equal to exactly 0.45359237 kilogram.
From Latin 'libra pondo' (a pound by weight); the symbol lb comes from 'libra'.
The primary weight unit in the United States and informally in the UK.
The international avoirdupois pound was fixed in the 1959 yard-and-pound agreement.

Real-world example — Children's height milestones
A 150-ton (assay) (us)-tall child measures a value in pounds that's commonly used for theme-park ride height requirements when travelling between countries that use different measurement units.
150 AT × 0.0643015005 = 9.6452250729 lb
Real-world example — Body height conversion
You enter your height as 180 tons (assay) (us) into an international job or visa application. The form then asks for the same value in pounds — converting between these adjacent units is one of the most-used length conversions globally.
180 AT × 0.0643015005 = 11.5742700875 lb
Real-world example — Furniture and large objects
A 72-ton (assay) (us) piece of furniture converts to a value in pounds that's easier to mentally compare with room dimensions. This is the typical workflow when shopping internationally and product specs use a different unit than your room measurements.
72 AT × 0.0643015005 = 4.629708035 lb
