Units explained
Microgram
A microgram (ug) equals 10^-9 kilogram, or one-millionth of a gram.
From the SI prefix 'micro-' (from Greek 'mikros', small).
Trace nutrients, potent drug doses, and environmental contaminant levels.
The micro- prefix was incorporated into the SI in 1960.
Ton (assay) (UK)
The assay ton (UK) equals about 32.667 grams, the long-ton analog of the assay ton.
The long-ton version of the assay-ton convenience unit.
Ore assaying in long-ton (imperial) contexts.
Adopted in assay laboratories using the long ton.
Microgram to Ton (assay) (UK) conversion formula
The relationship between micrograms and tons (assay) (uk):
To convert micrograms to tons (assay) (uk), multiply the value in micrograms by 3.061224e-8. To reverse, multiply tons (assay) (uk) by 3.266667e+7.

Worked examples
Example 1 — Convert 1 µg to AT:
1 × 3.061224e-8 = 3.061224e-8 AT
Example 2 — Convert 100 µg to AT:
100 × 3.061224e-8 = 3.061224e-6 AT
Real-world example — Sub-micron to millimeter
500,000 micrograms converts to a small everyday quantity in tons (assay) (uk) — useful when relating optical-wavelength specifications to physical mounting hardware.
500000 µg × 3.061224e-8 = 0.0153061224 AT
Real-world example — From wavelengths to millimeter-scale objects
A value of one million micrograms sounds vast at the atomic scale but converts to a small everyday quantity in tons (assay) (uk) — useful when relating optical-wavelength specifications to physical mounting hardware.
1000000 µg × 3.061224e-8 = 0.0306122449 AT
