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.

Metric / SI

Decigram

What is a decigram?

A decigram (dg) equals 0.0001 kilogram, or 0.1 gram.

Origin of the decigram

From the SI prefix 'deci-' (from Latin 'decimus', tenth).

Where it is used

Occasional laboratory and pharmacy use.

When and where it was developed

Part of the original metric system of 1795.

Ton (assay) (UK) to Decigram conversion formula

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

1 AT = 326.666667 dg

1 dg = 0.0030612245 AT

To convert tons (assay) (uk) to decigrams, multiply the value in tons (assay) (uk) by 326.666667. To reverse, multiply decigrams by 0.0030612245.

How to use this converter

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

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

Write down the value in tons (assay) (uk) (AT).
Multiply that value by the factor 326.666667.
The product is the equivalent value in decigrams (dg).
To reverse, multiply the decigram value by 0.0030612245.

Worked examples

Example 1 — Convert 1 AT to dg:
1 × 326.666667 = 326.666667 dg

Example 2 — Convert 100 AT to dg:
100 × 326.666667 = 32666.6667 dg

Real-world example — Adjacent metric sub-units

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

1 AT × 326.666667 = 326.666667 dg

Real-world example — Adjacent small-scale precision

One ton (assay) (uk) equals 1,000 decigrams — 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 × 326.666667 = 326.666667 dg
