Convert Millirads per hour to Rads per second
Convert Millirads per hour (mrad/h) to Rads per second (rad/s) instantly and accurately.
Conversion Formula
rad/s = mrad/h × 2.777777778e-7
About Millirads per hour
The millirad per hour (mrad/h) equals 1e-5 Gy/h = 10 µGy/h. Legacy US radiation protection unit used by area monitors and Geiger counters calibrated before SI adoption; EPA environmental surveillance stations report in mrad/h alongside µGy/h; NRC licence boundary dose-rate surveys often cite mrad/h. 1 mrad/h = 1e-5 Gy/h = 10 µGy/h.
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.
