Units explained
Centigram
A centigram (cg) equals 0.00001 kilogram, or 0.01 gram.
From the SI prefix 'centi-' (from Latin 'centum', hundred).
Used in pharmacology and analytical chemistry.
Part of the original metric system of 1795.
Wey
The wey was an English bulk weight, here taken as 252 pounds (about 114.3 kg).
From Old English 'waege', a weighing or balance.
Obsolete English unit for wool, cheese, and salt.
Used in medieval and early-modern English trade.

Real-world example — Plastic-film thickness alternates
A 150-centigram plastic film converts cleanly to weys — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.
150 cg × 8.748502e-8 = 1.312275e-5 wey
Real-world example — Hair-width scale measurements
A 70-centigram measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like weys for direct comparison across supplier datasheets.
70 cg × 8.748502e-8 = 6.123952e-6 wey
Real-world example — Paper and film thicknesses
At the thickness of office paper (roughly 3 centigrams), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.
3 cg × 8.748502e-8 = 2.624551e-7 wey
