Convert Grays per second to Grays per hour
Convert Grays per second (Gy/s) to Grays per hour (Gy/h) instantly and accurately.
Conversion Formula
Gy/h = Gy/s × 3600
About Grays per second
The gray per second (Gy/s) is the SI coherent unit of absorbed dose rate, equal to 1 joule per kilogram per second, dimensionally equivalent to W/kg or m²/s³. Used in HDR brachytherapy source strength, FLASH radiotherapy research (>40 Gy/s for normal tissue sparing), and particle accelerator beam-loss dosimetry. 1 Gy/s = 60 Gy/min = 3600 Gy/h = 100 rad/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.
