Ton (assay) (UK)

What is a ton (assay) (uk)?

The assay ton (UK) equals about 32.667 grams, the long-ton analog of the assay ton.

Origin of the ton (assay) (uk)

The long-ton version of the assay-ton convenience unit.

Where it is used

Ore assaying in long-ton (imperial) contexts.

When and where it was developed

Adopted in assay laboratories using the long ton.

Avoirdupois

Grain

What is a grain?

The grain (gr) equals 1/7000 of an avoirdupois pound, about 64.8 milligrams.

Origin of the grain

Based on the nominal mass of a single barley grain.

Where it is used

Ammunition and bullet mass, archery, and historical pharmacy.

When and where it was developed

Standardized through the English avoirdupois system and retained in 1959.

Ton (assay) (UK) to Grain conversion formula

The relationship between tons (assay) (uk) and grains:

1 AT = 504.1237845087 gr
1 gr = 0.0019836398 AT

To convert tons (assay) (uk) to grains, multiply the value in tons (assay) (uk) by 504.1237845087. To reverse, multiply grains by 0.0019836398.

Type a value into the calculator. The result in grains updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Grain to Ton (assay) (UK) converter for the reverse direction.

Step-by-step: convert tons (assay) (uk) to grains

  1. Write down the value in tons (assay) (uk) (AT).
  2. Multiply that value by the factor 504.1237845087.
  3. The product is the equivalent value in grains (gr).
  4. To reverse, multiply the grain value by 0.0019836398.

Worked examples

Example 1 — Convert 1 AT to gr:
1 × 504.1237845087 = 504.1237845087 gr

Example 2 — Convert 100 AT to gr:
100 × 504.1237845087 = 50412.3784508688 gr

Real-world example — Adjacent small-scale precision

One ton (assay) (uk) equals 1,000 grains — the standard sub-millimeter precision conversion that materials engineers use whenever they switch between bulk material thickness specs (larger unit) and surface-finish characteristics (smaller unit).

1 AT × 504.1237845087 = 504.1237845087 gr

Real-world example — Adjacent metric sub-units

One ton (assay) (uk) equals 1,000 grains. Engineers move between these scales constantly: PCB feature sizes in the larger unit, wire-bond diameters in the smaller.

1 AT × 504.1237845087 = 504.1237845087 gr
