Units explained
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.
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.
Femtogram to Decigram conversion formula
The relationship between femtograms and decigrams:
To convert femtograms to decigrams, multiply the value in femtograms by 1e-14. To reverse, multiply decigrams by 1e+14.
How to use this converter
Type a value into the calculator. The result in decigrams updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Decigram to Femtogram converter for the reverse direction.
Step-by-step: convert femtograms to decigrams
- Write down the value in femtograms (fg).
- Multiply that value by the factor 1e-14.
- The product is the equivalent value in decigrams (dg).
- To reverse, multiply the decigram value by 1e+14.
Worked examples
Example 1 — Convert 1 fg to dg:
1 × 1e-14 = 1e-14 dg
Example 2 — Convert 100 fg to dg:
100 × 1e-14 = 1e-12 dg
Real-world example — Spanning sub-micron to micron scale
Crossing from femtograms to decigrams is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 femtograms translates to a much more compact value in decigrams that fits the scale of biological cells and process nodes.
1000 fg × 1e-14 = 1e-11 dg
Real-world example — Sub-visible-light wavelength
500 femtograms (the green-yellow visible band) equals 0.5 decigrams — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 fg × 1e-14 = 5e-12 dg
