What does 1 picogray represent in gray?

One picogray (pGy) equals 1×10^-12 gray (Gy), quantifying very small amounts of absorbed radiation energy.

In what contexts is the conversion from picogray to gray most useful?

It is commonly used in radiation dosimetry labs, environmental radiation monitoring, space instrumentation, and radiotherapy treatment planning.

Does this conversion account for biological effects of radiation?

No, this conversion relates only to physical absorbed dose; biological effects require conversion to sieverts which involves additional weighting.
