Are joule per kilogram and gray the same unit?

Yes, 1 joule per kilogram is exactly equal to 1 gray. Both measure the physical absorbed dose of ionizing radiation.

Why convert between joule/kilogram and gray?

Converting between these units helps standardize radiation dose measurements commonly used in medicine, health physics, and research.

Does this conversion reflect the biological effect of radiation?

No, it only represents absorbed energy. Biological impact requires additional conversion using weighting factors into units like sieverts.
