Units explained
Quintal (metric)
The metric quintal (q) equals 100 kilograms.
From Latin 'centenarius' (hundredweight) via Arabic 'qintar'.
Agriculture across India, Europe, and Latin America for grain and produce.
Fixed at 100 kg with the spread of the metric system in the 19th century.
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.
Quintal (metric) to Exagram conversion formula
The relationship between quintals (metric) and exagrams:
To convert quintals (metric) to exagrams, multiply the value in quintals (metric) by 1e-13. To reverse, multiply exagrams by 1e+13.
How to use this converter

Step-by-step: convert quintals (metric) to exagrams
- Write down the value in quintals (metric) (q).
- Multiply that value by the factor 1e-13.
- The product is the equivalent value in exagrams (Eg).
- To reverse, multiply the exagram value by 1e+13.
Worked examples
Example 1 — Convert 1 q to Eg:
1 × 1e-13 = 1e-13 Eg
Example 2 — Convert 100 q to Eg:
100 × 1e-13 = 1e-11 Eg
