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.
Femtogram
A femtogram (fg) equals 10^-18 kilogram.
From the SI prefix 'femto-' (from Danish/Norwegian 'femten', fifteen).
Nanotechnology and high-sensitivity mass spectrometry.
The femto- prefix was adopted by the CGPM in 1975.
Quintal (metric) to Femtogram conversion formula
The relationship between quintals (metric) and femtograms:
To convert quintals (metric) to femtograms, multiply the value in quintals (metric) by 1e+20. To reverse, multiply femtograms by 1e-20.

Step-by-step: convert quintals (metric) to femtograms
- Write down the value in quintals (metric) (q).
- Multiply that value by the factor 1e+20.
- The product is the equivalent value in femtograms (fg).
- To reverse, multiply the femtogram value by 1e-20.
Worked examples
Example 1 — Convert 1 q to fg:
1 × 1e+20 = 1e+20 fg
Example 2 — Convert 100 q to fg:
100 × 1e+20 = 1e+22 fg
