Convert decigrams to exagrams instantly. 1 decigram = 1e-19 exagram — use the live calculator, the exact formula, a conversion table and worked examples. Also check the Exagram to Decigram converter for the reverse conversion.
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.
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.
Decigram to Exagram conversion formula
The relationship between decigrams and exagrams:
To convert decigrams to exagrams, multiply the value in decigrams by 1e-19. To reverse, multiply exagrams by 1e+19.
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 Decigram converter for the reverse direction.
Step-by-step: convert decigrams to exagrams
- Write down the value in decigrams (dg).
- Multiply that value by the factor 1e-19.
- The product is the equivalent value in exagrams (Eg).
- To reverse, multiply the exagram value by 1e+19.
Worked examples
Example 1 — Convert 1 dg to Eg:
1 × 1e-19 = 1e-19 Eg
Example 2 — Convert 100 dg to Eg:
100 × 1e-19 = 1e-17 Eg
Real-world example — Plastic-film thickness alternates
A 150-decigram plastic film converts cleanly to exagrams — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.
150 dg × 1e-19 = 1.5e-17 Eg
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 exagrams for direct comparison across supplier datasheets.
70 dg × 1e-19 = 7e-18 Eg
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 × 1e-19 = 3e-19 Eg
