Convert Rads per second to Grays per hour

Convert Rads per second (rad/s) to Grays per hour (Gy/h) instantly and accurately.

Rads per second (rad/s)
Grays per hour (Gy/h)

Conversion Formula

Gy/h = rad/s × 36

About Rads per second

The rad per second (rad/s) equals 0.01 Gy/s. Used in US radiation therapy physics and pulsed accelerator dosimetry: FLASH radiotherapy (FLASH-RT) research defines ultra-high dose rate as >40 Gy/s = 4000 rad/s; linac prompt radiation dose rates during pulsed operation are characterised in rad/s; nuclear detonation prompt gamma fields are described in rad/s. 1 rad/s = 0.01 Gy/s = 1 cGy/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.
