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.

Carat (metric)

What is a carat (metric)?

The metric carat (ct) equals exactly 200 milligrams (0.0002 kg).

Origin of the carat (metric)

From Arabic 'qirat' and Greek 'keration', the carob seed once used as a counterweight.

Where it is used

The worldwide standard for gemstone and diamond mass.

When and where it was developed

The metric carat was fixed at 200 mg internationally in 1907.

Ton (assay) (UK) to Carat (metric) conversion formula

The relationship between tons (assay) (uk) and carats (metric):

1 AT = 163.3333335 ct
1 ct = 0.006122449 AT

To convert tons (assay) (uk) to carats (metric), multiply the value in tons (assay) (uk) by 163.3333335. To reverse, multiply carats (metric) by 0.006122449.

How to use this converter

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

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

  1. Write down the value in tons (assay) (uk) (AT).
  2. Multiply that value by the factor 163.3333335.
  3. The product is the equivalent value in carats (metric) (ct).
  4. To reverse, multiply the carat (metric) value by 0.006122449.

Worked examples

Example 1 — Convert 1 AT to ct:
1 × 163.3333335 = 163.3333335 ct

Example 2 — Convert 100 AT to ct:
100 × 163.3333335 = 16333.33335 ct

Real-world example — Adjacent small-scale precision

One ton (assay) (uk) equals 1,000 carats (metric) — 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 × 163.3333335 = 163.3333335 ct

Real-world example — Adjacent metric sub-units

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

1 AT × 163.3333335 = 163.3333335 ct
