Units explained
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.
Milligram
A milligram (mg) equals one-millionth of a kilogram, or 0.001 gram.
From the SI prefix 'milli-' (from Latin 'mille', thousand).
Standard for medicine dosing, nutrition labels, and fine jewelry.
Part of the original metric system of 1795.
Decigram to Milligram conversion formula
The relationship between decigrams and milligrams:
To convert decigrams to milligrams, multiply the value in decigrams by 100. To reverse, multiply milligrams by 0.01.

Step-by-step: convert decigrams to milligrams
- Write down the value in decigrams (dg).
- Multiply that value by the factor 100.
- The product is the equivalent value in milligrams (mg).
- To reverse, multiply the milligram value by 0.01.
Worked examples
Example 1 — Convert 1 dg to mg:
1 × 100 = 100 mg
Example 2 — Convert 100 dg to mg:
100 × 100 = 10000 mg
Real-world example — Plastic-film thickness alternates
A 150-decigram plastic film converts cleanly to milligrams — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.
150 dg × 100 = 15000 mg
Real-world example — Hair-width scale measurements
A 70-decigram measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like milligrams for direct comparison across supplier datasheets.
70 dg × 100 = 7000 mg
Real-world example — Paper and film thicknesses
At the thickness of office paper (roughly 3 decigrams), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.
3 dg × 100 = 300 mg
