Units explained
Nanogram
A nanogram (ng) equals 10^-12 kilogram.
From the SI prefix 'nano-' (from Greek 'nanos', dwarf).
Molecular biology, forensics, and toxicology.
The nano- prefix entered the SI in 1960.
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.
Nanogram to Decigram conversion formula
The relationship between nanograms and decigrams:
To convert nanograms to decigrams, multiply the value in nanograms by 1e-8. To reverse, multiply decigrams by 1e+8.
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 Nanogram converter for the reverse direction.
Step-by-step: convert nanograms to decigrams
- Write down the value in nanograms (ng).
- Multiply that value by the factor 1e-8.
- The product is the equivalent value in decigrams (dg).
- To reverse, multiply the decigram value by 1e+8.
Worked examples
Example 1 — Convert 1 ng to dg:
1 × 1e-8 = 1e-8 dg
Example 2 — Convert 100 ng to dg:
100 × 1e-8 = 1e-6 dg
Real-world example — Spanning sub-micron to micron scale
Crossing from nanograms to decigrams is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 nanograms translates to a much more compact value in decigrams that fits the scale of biological cells and process nodes.
1000 ng × 1e-8 = 1e-5 dg
Real-world example — Sub-visible-light wavelength
500 nanograms (the green-yellow visible band) equals 0.5 decigrams — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 ng × 1e-8 = 5e-6 dg
