picogray to nanogray
Convert picogray (pGy) to nanogray (nGy). Use an editable absorbed dose converter, conversion formula, and reference table.
1 pGy = 0.001 nGy
Conversion formula
One picogray equals 0.001 nanogray. Multiply your value in picogray by this factor to get nanogray. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 picogray:5 × 0.001 = 0.005 nGy

About these measurements
Absorbed dose measures energy deposited per unit mass.
The base reference used here is the gray. One picogray is 1e-12 base units; one nanogray is 1e-9 base units.
Important distinctions
Physical unit conversion only. Biological effect requires additional information and professional assessment.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
