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.
Picogram
A picogram (pg) equals 10^-15 kilogram.
From the SI prefix 'pico-' (from Spanish 'pico', a small quantity).
Single-cell biology and ultratrace chemical analysis.
The pico- prefix entered the SI in 1960.
Nanogram to Picogram conversion formula
The relationship between nanograms and picograms:
To convert nanograms to picograms, multiply the value in nanograms by 1000. To reverse, multiply picograms by 0.001.
How to use this converter
Type a value into the calculator. The result in picograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Picogram to Nanogram converter for the reverse direction.
Step-by-step: convert nanograms to picograms
- Write down the value in nanograms (ng).
- Multiply that value by the factor 1000.
- The product is the equivalent value in picograms (pg).
- To reverse, multiply the picogram value by 0.001.
Worked examples
Example 1 — Convert 1 ng to pg:
1 × 1000 = 1000 pg
Example 2 — Convert 100 ng to pg:
100 × 1000 = 100000 pg
Real-world example — Wavelengths across the spectrum
Optical and atomic-scale phenomena are routinely cross-converted between sub-micron units. A photon of wavelength 800 nanograms can be re-expressed in picograms for direct comparison with another instrument's calibration data sheet.
800 ng × 1000 = 799999.9999999999 pg
Real-world example — Molecular dimensions
The diameter of small molecular structures (around 2 nanograms) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.
2 ng × 1000 = 2000 pg
