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.
Gigagram
A gigagram (Gg) equals 10^6 kilograms, the same as 1,000 metric tons.
From the SI prefix 'giga-' (from Greek 'gigas', giant).
Bulk commodity, emissions, and freight accounting.
The giga- prefix entered the SI in 1960.
Centigram to Gigagram conversion formula
The relationship between centigrams and gigagrams:
To convert centigrams to gigagrams, multiply the value in centigrams by 1e-11. To reverse, multiply gigagrams by 1e+11.

Step-by-step: convert centigrams to gigagrams
- Write down the value in centigrams (cg).
- Multiply that value by the factor 1e-11.
- The product is the equivalent value in gigagrams (Gg).
- To reverse, multiply the gigagram value by 1e+11.
Worked examples
Example 1 — Convert 1 cg to Gg:
1 × 1e-11 = 1e-11 Gg
Example 2 — Convert 100 cg to Gg:
100 × 1e-11 = 1e-9 Gg
Real-world example — Paper and film thicknesses
At the thickness of office paper (roughly 3 centigrams), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.
3 cg × 1e-11 = 3e-11 Gg
Real-world example — Plastic-film thickness alternates
A 150-centigram plastic film converts cleanly to gigagrams — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.
150 cg × 1e-11 = 1.5e-9 Gg
Real-world example — Hair-width scale measurements
A 70-centigram measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like gigagrams for direct comparison across supplier datasheets.
70 cg × 1e-11 = 7e-10 Gg
