Units explained
Attogram
An attogram (ag) equals 10^-21 kilogram.
From the SI prefix 'atto-' (from Danish 'atten', eighteen).
Frontier nanoscience and single-molecule mass detection.
The atto- 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.
Attogram to Decigram conversion formula
The relationship between attograms and decigrams:
To convert attograms to decigrams, multiply the value in attograms by 1e-17. To reverse, multiply decigrams by 1e+17.

Step-by-step: convert attograms to decigrams
- Write down the value in attograms (ag).
- Multiply that value by the factor 1e-17.
- The product is the equivalent value in decigrams (dg).
- To reverse, multiply the decigram value by 1e+17.
Worked examples
Example 1 — Convert 1 ag to dg:
1 × 1e-17 = 1e-17 dg
Example 2 — Convert 100 ag to dg:
100 × 1e-17 = 1e-15 dg
Real-world example — Spanning sub-micron to micron scale
Crossing from attograms to decigrams is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 attograms translates to a much more compact value in decigrams that fits the scale of biological cells and process nodes.
1000 ag × 1e-17 = 1e-14 dg
Real-world example — Sub-visible-light wavelength
500 attograms (the green-yellow visible band) equals 0.5 decigrams — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 ag × 1e-17 = 5e-15 dg
