What Is This Tool?
This converter helps you change radiation absorbed dose measurements from nanogray (nGy) to joule per kilogram (J/kg). Nanogray is used for very small radiation doses, while joule per kilogram is the SI base unit to quantify energy deposited by radiation in materials. The tool supports accurate and standardized unit conversions essential for environmental, medical, and scientific applications.
