Units explained
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.
Grain
The grain (gr) equals 1/7000 of an avoirdupois pound, about 64.8 milligrams.
Based on the nominal mass of a single barley grain.
Ammunition and bullet mass, archery, and historical pharmacy.
Standardized through the English avoirdupois system and retained in 1959.

Worked examples
Example 1 — Convert 1 dg to gr:
1 × 1.5432360735 = 1.5432360735 gr
Example 2 — Convert 100 dg to gr:
100 × 1.5432360735 = 154.3236073452 gr
Real-world example — Hair-width scale measurements
A 70-decigram measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like grains for direct comparison across supplier datasheets.
70 dg × 1.5432360735 = 108.0265251416 gr
Real-world example — Paper and film thicknesses
At the thickness of office paper (roughly 3 decigrams), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.
3 dg × 1.5432360735 = 4.6297082204 gr
Real-world example — Plastic-film thickness alternates
A 150-decigram plastic film converts cleanly to grains — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.
150 dg × 1.5432360735 = 231.4854110178 gr
