Units explained
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.
Microgram
A microgram (ug) equals 10^-9 kilogram, or one-millionth of a gram.
From the SI prefix 'micro-' (from Greek 'mikros', small).
Trace nutrients, potent drug doses, and environmental contaminant levels.
The micro- prefix was incorporated into the SI in 1960.
Picogram to Microgram conversion formula
The relationship between picograms and micrograms:
To convert picograms to micrograms, multiply the value in picograms by 1e-6. To reverse, multiply micrograms by 1000000.
How to use this converter
Type a value into the calculator. The result in micrograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Microgram to Picogram converter for the reverse direction.
Step-by-step: convert picograms to micrograms
- Write down the value in picograms (pg).
- Multiply that value by the factor 1e-6.
- The product is the equivalent value in micrograms (µg).
- To reverse, multiply the microgram value by 1000000.
Worked examples
Example 1 — Convert 1 pg to µg:
1 × 1e-6 = 1e-6 µg
Example 2 — Convert 100 pg to µg:
100 × 1e-6 = 1e-4 µg
Real-world example — Molecular dimensions
The diameter of small molecular structures (around 2 picograms) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.
2 pg × 1e-6 = 2e-6 µg
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 picograms can be re-expressed in micrograms for direct comparison with another instrument's calibration data sheet.
800 pg × 1e-6 = 0.0008 µg
