Units explained
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
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 to Picogram conversion formula
The relationship between centigrams and picograms:
To convert centigrams to picograms, multiply the value in centigrams by 1e+10. To reverse, multiply picograms by 1e-10.
How to use this converter
Type a value into the calculator. The result in picograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Picogram to Centigram converter for the reverse direction.
Step-by-step: convert centigrams to picograms
- Write down the value in centigrams (cg).
- Multiply that value by the factor 1e+10.
- The product is the equivalent value in picograms (pg).
- To reverse, multiply the picogram value by 1e-10.
Worked examples
Example 1 — Convert 1 cg to pg:
1 × 1e+10 = 1e+10 pg
Example 2 — Convert 100 cg to pg:
100 × 1e+10 = 1e+12 pg
Real-world example — Mid-micron to nanometer
3 centigrams equals 3,000 picograms — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.
3 cg × 1e+10 = 3e+10 pg
Real-world example — From microns to sub-micron features
One centigram equals one thousand picograms — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.
1 cg × 1e+10 = 1e+10 pg
Real-world example — Infrared to visible-spectrum mapping
A 10-centigram thermal infrared wavelength corresponds to a much larger number in picograms, the unit favoured for ultraviolet and visible-light specifications.
10 cg × 1e+10 = 1e+11 pg
