Units explained
Gram
The gram (g) equals one-thousandth of a kilogram.
From Late Latin 'gramma', a small weight or scruple.
The everyday metric unit for food, medicine, and small objects.
Defined in 1795 as the mass of one cubic centimeter of water at melting point.
Dekagram
A dekagram (dag) equals 0.01 kilogram, or 10 grams.
From the SI prefix 'deka-' (from Greek 'deka', ten).
Widely used in Central and Eastern European cooking and shops (dag/dkg).
Part of the original metric system introduced in 1795.
Gram to Dekagram conversion formula
The relationship between grams and dekagrams:
To convert grams to dekagrams, multiply the value in grams by 0.1. To reverse, multiply dekagrams by 10.

Step-by-step: convert grams to dekagrams
- Write down the value in grams (g).
- Multiply that value by the factor 0.1.
- The product is the equivalent value in dekagrams (dag).
- To reverse, multiply the dekagram value by 10.
Worked examples
Example 1 — Convert 1 g to dag:
1 × 0.1 = 0.1 dag
Example 2 — Convert 100 g to dag:
100 × 0.1 = 10 dag
Real-world example — Postcard and small-object dimensions
A postcard is about 5 grams wide. Converting to dekagrams is essential for international postal addressing forms that ask for dimensions in different units across countries.
5 g × 0.1 = 0.5 dag
Real-world example — Ruler-scale measurements
A 30-gram school ruler converts cleanly to dekagrams — useful when buying a desk accessory from a retailer whose product specs use a different unit.
30 g × 0.1 = 3 dag
Real-world example — Hardware-scale dimensions
A 10-gram fastener or component is about as long as a thumbnail. Mechanics and DIY enthusiasts convert between grams and dekagrams daily when mixing metric and imperial tools.
10 g × 0.1 = 1 dag
