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.
Centigram
A centigram (cg) equals 0.00001 kilogram, or 0.01 gram.
From the SI prefix 'centi-' (from Latin 'centum', hundred).
Used in pharmacology and analytical chemistry.
Part of the original metric system of 1795.
Picogram to Centigram conversion formula
The relationship between picograms and centigrams:
To convert picograms to centigrams, multiply the value in picograms by 1e-10. To reverse, multiply centigrams by 1e+10.

Step-by-step: convert picograms to centigrams
- Write down the value in picograms (pg).
- Multiply that value by the factor 1e-10.
- The product is the equivalent value in centigrams (cg).
- To reverse, multiply the centigram value by 1e+10.
Worked examples
Example 1 — Convert 1 pg to cg:
1 × 1e-10 = 1e-10 cg
Example 2 — Convert 100 pg to cg:
100 × 1e-10 = 1e-8 cg
Real-world example — Spanning sub-micron to micron scale
Crossing from picograms to centigrams is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 picograms translates to a much more compact value in centigrams that fits the scale of biological cells and process nodes.
1000 pg × 1e-10 = 1e-7 cg
Real-world example — Sub-visible-light wavelength
500 picograms (the green-yellow visible band) equals 0.5 centigrams — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 pg × 1e-10 = 5e-8 cg
