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.
Masha
The masha equals about 0.972 gram, or eight ratti.
A traditional Indian mass unit in the ratti-masha-tola chain.
Small jewelry and gemstone weights in South Asia.
Part of the ancient Indian weight system dating to the Indus Valley era.
Picogram to Masha 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 picograms and mashas:
To convert picograms to mashas, multiply the value in picograms by 1.028824e-12. To reverse, multiply mashas by 9.719837e+11.

Step-by-step: convert picograms to mashas
- Write down the value in picograms (pg).
- Multiply that value by the factor 1.028824e-12.
- The product is the equivalent value in mashas (masha).
- To reverse, multiply the masha value by 9.719837e+11.
Worked examples
Example 1 — Convert 1 pg to masha:
1 × 1.028824e-12 = 1.028824e-12 masha
Example 2 — Convert 100 pg to masha:
100 × 1.028824e-12 = 1.028824e-10 masha
Real-world example — Sub-visible-light wavelength
500 picograms (the green-yellow visible band) equals 0.5 mashas — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 pg × 1.028824e-12 = 5.144119e-10 masha
Real-world example — Spanning sub-micron to micron scale
Crossing from picograms to mashas is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 picograms translates to a much more compact value in mashas that fits the scale of biological cells and process nodes.
1000 pg × 1.028824e-12 = 1.028824e-9 masha
