Units explained
Stone (US)
A less common US definition of the stone, about 5.67 kilograms.
A variant stone weight used in some historical US trade.
Rare; appears mainly in historical or specialized contexts.
Derived from older English stone weights that varied by commodity.
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 st to ratti:
1 × 46665.8816872428 = 46665.8816872428 ratti
Example 2 — Convert 100 st to ratti:
100 × 46665.8816872428 = 4666588.1687242799 ratti
Real-world example — Macro-to-micro scale comparison
2 stones (us) 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 st × 46665.8816872428 = 93331.7633744856 ratti
Real-world example — Macroscopic to microscopic
One stone (us) equals a million rattis. Optical engineers calculating coherence length compare macro-scale path lengths with micro-scale wavelength differences using exactly this conversion.
1 st × 46665.8816872428 = 46665.8816872428 ratti
Real-world example — Sub-meter precision
A 0.001-stone (us) (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 st × 46665.8816872428 = 46.6658816872 ratti
