Units explained
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.
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.

Worked examples
Example 1 — Convert 1 masha to ct:
1 × 4.8599185 = 4.8599185 ct
Example 2 — Convert 100 masha to ct:
100 × 4.8599185 = 485.99185 ct
Real-world example — Hair-width scale measurements
A 70-masha measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like carats (metric) for direct comparison across supplier datasheets.
70 masha × 4.8599185 = 340.194295 ct
Real-world example — Paper and film thicknesses
At the thickness of office paper (roughly 3 mashas), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.
3 masha × 4.8599185 = 14.5797555 ct
Real-world example — Plastic-film thickness alternates
A 150-masha plastic film converts cleanly to carats (metric) — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.
150 masha × 4.8599185 = 728.987775 ct
