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.
Decigram
A decigram (dg) equals 0.0001 kilogram, or 0.1 gram.
From the SI prefix 'deci-' (from Latin 'decimus', tenth).
Occasional laboratory and pharmacy use.
Part of the original metric system of 1795.
Centigram to Decigram conversion formula
The relationship between centigrams and decigrams:
To convert centigrams to decigrams, multiply the value in centigrams by 0.1. To reverse, multiply decigrams by 10.
How to use this converter
Type a value into the calculator. The result in decigrams updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Decigram to Centigram converter for the reverse direction.
Step-by-step: convert centigrams to decigrams
- Write down the value in centigrams (cg).
- Multiply that value by the factor 0.1.
- The product is the equivalent value in decigrams (dg).
- To reverse, multiply the decigram value by 10.
Worked examples
Example 1 — Convert 1 cg to dg:
1 × 0.1 = 0.1 dg
Example 2 — Convert 100 cg to dg:
100 × 0.1 = 10 dg
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 × 0.1 = 0.3 dg
Real-world example — Plastic-film thickness alternates
A 150-centigram plastic film converts cleanly to decigrams — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.
150 cg × 0.1 = 15 dg
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 decigrams for direct comparison across supplier datasheets.
70 cg × 0.1 = 7 dg
