Convert between Gy, Sv, rad, rem and common prefixes. Sv ≈ Gy assumed for typical photon radiation — see note.

Note: This converter uses Gray (Gy) as the base unit. By default the tool treats 1 Sv ≈ 1 Gy (assumes radiation weighting factor = 1, typical for photons). For non-photon radiation or tissue-specific calculations, results will differ.
