teragray to picogray
Convert teragray (TGy) to picogray (pGy). Use an editable absorbed dose converter, conversion formula, and reference table.
1 TGy = 1e+24 pGy
Conversion formula
One teragray equals 1e+24 picogray. Multiply your value in teragray by this factor to get picogray. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 teragray:5 × 1e+24 = 5e+24 pGy

About these measurements
Absorbed dose measures energy deposited per unit mass.
The base reference used here is the gray. One teragray is 1e+12 base units; one picogray is 1e-12 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.
