Units explained
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
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 to Nanogram conversion formula
The relationship between decigrams and nanograms:
To convert decigrams to nanograms, multiply the value in decigrams by 1e+8. To reverse, multiply nanograms by 1e-8.
How to use this converter
Type a value into the calculator. The result in nanograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Nanogram to Decigram converter for the reverse direction.
Step-by-step: convert decigrams to nanograms
- Write down the value in decigrams (dg).
- Multiply that value by the factor 1e+8.
- The product is the equivalent value in nanograms (ng).
- To reverse, multiply the nanogram value by 1e-8.
Worked examples
Example 1 — Convert 1 dg to ng:
1 × 1e+8 = 1e+8 ng
Example 2 — Convert 100 dg to ng:
100 × 1e+8 = 1e+10 ng
Real-world example — Infrared to visible-spectrum mapping
A 10-decigram thermal infrared wavelength corresponds to a much larger number in nanograms, the unit favoured for ultraviolet and visible-light specifications.
10 dg × 1e+8 = 1e+9 ng
Real-world example — Mid-micron to nanometer
3 decigrams equals 3,000 nanograms — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.
3 dg × 1e+8 = 3e+8 ng
Real-world example — From microns to sub-micron features
One decigram equals one thousand nanograms — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.
1 dg × 1e+8 = 1e+8 ng
