Units explained
Proton Mass
The proton rest mass is about 1.6726E-27 kg.
The mass of the proton, the positively charged nucleon.
Nuclear and particle physics, and chemistry.
Quantified after Rutherford identified the proton around 1917-1920.
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.
Proton Mass 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 proton mass and rattis:
To convert proton mass to rattis, multiply the value in proton mass by 1.376645e-23. To reverse, multiply rattis by 7.264039e+22.

Step-by-step: convert proton mass to rattis
- Write down the value in proton mass (mp).
- Multiply that value by the factor 1.376645e-23.
- The product is the equivalent value in rattis (ratti).
- To reverse, multiply the ratti value by 7.264039e+22.
Worked examples
Example 1 — Convert 1 mp to ratti:
1 × 1.376645e-23 = 1.376645e-23 ratti
Example 2 — Convert 100 mp to ratti:
100 × 1.376645e-23 = 1.376645e-21 ratti
Real-world example — Sub-visible-light wavelength
500 proton mass (the green-yellow visible band) equals 0.5 rattis — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 mp × 1.376645e-23 = 6.883223e-21 ratti
Real-world example — Spanning sub-micron to micron scale
Crossing from proton mass to rattis is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 proton mass translates to a much more compact value in rattis that fits the scale of biological cells and process nodes.
1000 mp × 1.376645e-23 = 1.376645e-20 ratti
