Units explained
Picogram
A picogram (pg) equals 10^-15 kilogram.
From the SI prefix 'pico-' (from Spanish 'pico', a small quantity).
Single-cell biology and ultratrace chemical analysis.
The pico- prefix entered the SI in 1960.
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 pg to ratti:
1 × 8.230453e-12 = 8.230453e-12 ratti
Example 2 — Convert 100 pg to ratti:
100 × 8.230453e-12 = 8.230453e-10 ratti
Real-world example — Spanning sub-micron to micron scale
Crossing from picograms to rattis is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 picograms translates to a much more compact value in rattis that fits the scale of biological cells and process nodes.
1000 pg × 8.230453e-12 = 8.230453e-9 ratti
Real-world example — Sub-visible-light wavelength
500 picograms (the green-yellow visible band) equals 0.5 rattis — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 pg × 8.230453e-12 = 4.115226e-9 ratti
