Convert absorbed radiation dose across 10 units: SI (Gy, mGy, μGy, kGy, cGy, J/kg) and Traditional (rad, mrad, μrad, erg/g). 1 Gy = 100 rad = 1 J/kg (exact); 1 rad = 100 erg/g (exact). Quick-reference: chest X-ray (0.1–1 mGy), radiation therapy (60–80 Gy total), LD50 whole-body (4–5 Gy), food irradiation (0.5–50 kGy). Scientific notation spans μrad to kGy (14 orders of magnitude). 100% browser-based.
