Units explained
Microgram
A microgram (ug) equals 10^-9 kilogram, or one-millionth of a gram.
From the SI prefix 'micro-' (from Greek 'mikros', small).
Trace nutrients, potent drug doses, and environmental contaminant levels.
The micro- prefix was incorporated into 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.
Microgram to Ratti conversion formula
Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.
The relationship between micrograms and rattis:
To convert micrograms to rattis, multiply the value in micrograms by 8.230453e-6. To reverse, multiply rattis by 121500.

Step-by-step: convert micrograms to rattis
- Write down the value in micrograms (µg).
- Multiply that value by the factor 8.230453e-6.
- The product is the equivalent value in rattis (ratti).
- To reverse, multiply the ratti value by 121500.
Worked examples
Example 1 — Convert 1 µg to ratti:
1 × 8.230453e-6 = 8.230453e-6 ratti
Example 2 — Convert 100 µg to ratti:
100 × 8.230453e-6 = 0.0008230453 ratti
Real-world example — Spanning sub-micron to micron scale
Crossing from micrograms to rattis is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 micrograms translates to a much more compact value in rattis that fits the scale of biological cells and process nodes.
1000 µg × 8.230453e-6 = 0.0082304527 ratti
Real-world example — Sub-visible-light wavelength
500 micrograms (the green-yellow visible band) equals 0.5 rattis — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 µg × 8.230453e-6 = 0.0041152263 ratti
