Units explained
Tael
The tael equals about 37.8 grams (ten mace).
From Malay 'tahil'; the Chinese unit is the 'liang'.
East Asian precious-metal and traditional-medicine commerce.
A long-standing East Asian trade weight, with regional variants.
Carat (metric)
The metric carat (ct) equals exactly 200 milligrams (0.0002 kg).
From Arabic 'qirat' and Greek 'keration', the carob seed once used as a counterweight.
The worldwide standard for gemstone and diamond mass.
The metric carat was fixed at 200 mg internationally in 1907.

Real-world example — Adjacent small-scale precision
One tael 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 tael × 188.9968 = 188.9968 ct
Real-world example — Adjacent metric sub-units
One tael 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 tael × 188.9968 = 188.9968 ct
