Units explained
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.
Exagram
An exagram (Eg) equals 10^15 kilograms, or one quintillion grams.
From the SI prefix 'exa-' (from Greek 'hex', six, denoting the sixth power of 1000).
Confined to planetary- and atmospheric-scale mass discussions; never used in daily measurement.
The exa- prefix was adopted by the General Conference on Weights and Measures (CGPM) in 1975.
Dekagram to Exagram conversion formula
The relationship between dekagrams and exagrams:
To convert dekagrams to exagrams, multiply the value in dekagrams by 1e-17. To reverse, multiply exagrams by 1e+17.
How to use this converter
Type a value into the calculator. The result in exagrams updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Exagram to Dekagram converter for the reverse direction.
Step-by-step: convert dekagrams to exagrams
- Write down the value in dekagrams (dag).
- Multiply that value by the factor 1e-17.
- The product is the equivalent value in exagrams (Eg).
- To reverse, multiply the exagram value by 1e+17.
Worked examples
Example 1 — Convert 1 dag to Eg:
1 × 1e-17 = 1e-17 Eg
Example 2 — Convert 100 dag to Eg:
100 × 1e-17 = 1e-15 Eg
Real-world example — Hardware-scale dimensions
A 10-dekagram fastener or component is about as long as a thumbnail. Mechanics and DIY enthusiasts convert between dekagrams and exagrams daily when mixing metric and imperial tools.
10 dag × 1e-17 = 1e-16 Eg
Real-world example — Postcard and small-object dimensions
A postcard is about 5 dekagrams wide. Converting to exagrams is essential for international postal addressing forms that ask for dimensions in different units across countries.
5 dag × 1e-17 = 5e-17 Eg
Real-world example — Ruler-scale measurements
A 30-dekagram school ruler converts cleanly to exagrams — useful when buying a desk accessory from a retailer whose product specs use a different unit.
30 dag × 1e-17 = 3e-16 Eg
