Units explained
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.
Masha
The masha equals about 0.972 gram, or eight ratti.
A traditional Indian mass unit in the ratti-masha-tola chain.
Small jewelry and gemstone weights in South Asia.
Part of the ancient Indian weight system dating to the Indus Valley era.

Worked examples
Example 1 — Convert 1 gr to masha:
1 × 0.0666666529 = 0.0666666529 masha
Example 2 — Convert 100 gr to masha:
100 × 0.0666666529 = 6.6666652949 masha
Real-world example — Hair-width scale measurements
A 70-grain measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like mashas for direct comparison across supplier datasheets.
70 gr × 0.0666666529 = 4.6666657064 masha
Real-world example — Paper and film thicknesses
At the thickness of office paper (roughly 3 grains), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.
3 gr × 0.0666666529 = 0.1999999588 masha
Real-world example — Plastic-film thickness alternates
A 150-grain plastic film converts cleanly to mashas — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.
150 gr × 0.0666666529 = 9.9999979424 masha
