Ton (assay) (US)

What is a ton (assay) (us)?

The assay ton (US) equals about 29.167 grams, a mining-assay convenience unit.

Origin of the ton (assay) (us)

Devised so an assay sample's metal in milligrams reads as troy ounces per short ton.

Where it is used

Ore assaying and metallurgy.

When and where it was developed

Adopted in assay laboratories to simplify ore-grade calculation.

Force / Engineering

Slug

What is a slug?

The slug is the mass that accelerates at 1 ft/s^2 under a force of one pound-force, about 14.59 kg.

Origin of the slug

Coined in the early 20th century for the British gravitational (engineering) system.

Where it is used

US and British engineering dynamics.

When and where it was developed

Introduced in the British gravitational system of units.

Ton (assay) (US) to Slug conversion formula
