Convert Grays per minute to Grays per hour
Convert Grays per minute (Gy/min) to Grays per hour (Gy/h) instantly and accurately.
Conversion Formula
Gy/h = Gy/min × 60
About Grays per minute
The gray per minute (Gy/min) is the primary clinical radiotherapy machine output unit. Standard linac dose rates are 1-6 Gy/min at isocentre; stereotactic body radiotherapy (SBRT) uses up to 10 Gy/min; ¹⁹²Ir HDR brachytherapy sources are characterised in Gy/min at 1 cm reference distance. 1 Gy/min = 100 rad/min ≈ 1.67×10⁻² Gy/s.
About Grays per hour
The gray per hour (Gy/h) equals 1/3600 Gy/s ≈ 2.78×10⁻⁴ Gy/s. Used in radiation processing and source strength reporting: ¹³⁷Cs irradiator calibrations are expressed in Gy/h at a reference distance; IAEA food irradiation standards cite Gy/h for conveyor output; radiobiological experiments for cancer cell survival curves use Gy/h. 1 Gy/h = 100 rad/h = 1000 mGy/h.
