Units explained
Momme
The momme (mom) equals 3.75 grams.
A traditional Japanese mass unit (Japanese 'monme').
Pearls, and as the standard weight grade for silk fabric.
Part of the traditional Japanese shakkanho system.
Decigram
A decigram (dg) equals 0.0001 kilogram, or 0.1 gram.
From the SI prefix 'deci-' (from Latin 'decimus', tenth).
Occasional laboratory and pharmacy use.
Part of the original metric system of 1795.

Worked examples
Example 1 — Convert 1 mom to dg:
1 × 37.5 = 37.5 dg
Example 2 — Convert 100 mom to dg:
100 × 37.5 = 3750 dg
Real-world example — Adjacent metric sub-units
One momme equals 1,000 decigrams. Engineers move between these scales constantly: PCB feature sizes in the larger unit, wire-bond diameters in the smaller.
1 mom × 37.5 = 37.5 dg
Real-world example — Adjacent small-scale precision
One momme 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 mom × 37.5 = 37.5 dg
