Units explained
Hectogram
A hectogram (hg) equals 0.1 kilogram, or 100 grams.
From the SI prefix 'hecto-' (from Greek 'hekaton', hundred).
Common in continental European food retail, especially Italy ('etto').
The hecto- prefix dates to the original metric system of 1795.
Ratti
The ratti equals about 0.1215 gram, the smallest traditional South Asian weight.
Based on the seed of the Gunja plant (Abrus precatorius), or 'raktika' in Sanskrit.
Gemstones and gold in Indian and South Asian jewelry.
One of the oldest weight units of the Indian subcontinent, later standardized.

Worked examples
Example 1 — Convert 1 hg to ratti:
1 × 823.0452674897 = 823.0452674897 ratti
Example 2 — Convert 100 hg to ratti:
100 × 823.0452674897 = 82304.5267489712 ratti
Real-world example — Sub-meter precision
A 0.001-hectogram (1 mm) tolerance equals 1,000 rattis — useful for surface-finish specs, where macro-scale dimensions are given in the larger unit but feature roughness in the smaller.
0.001 hg × 823.0452674897 = 0.8230452675 ratti
Real-world example — Macro-to-micro scale comparison
2 hectograms of measurement converts to a very large number in rattis — useful in materials science when comparing bulk-sample dimensions to feature-level surface specs.
2 hg × 823.0452674897 = 1646.0905349794 ratti
Real-world example — Macroscopic to microscopic
One hectogram equals a million rattis. Optical engineers calculating coherence length compare macro-scale path lengths with micro-scale wavelength differences using exactly this conversion.
1 hg × 823.0452674897 = 823.0452674897 ratti
