Convert Millisieverts per hour to Grays per second
Convert Millisieverts per hour (mSv/h) to Grays per second (Gy/s) instantly and accurately.
Conversion Formula
Gy/s = mSv/h × 2.777777778e-7
About Millisieverts per hour
The millisievert per hour (mSv/h) equals 1e-3 Sv/h = 1e-3 Gy/h for photon radiation. Standard field survey unit in radiation protection: nuclear power plant boundary limits are stated in mSv/h; NRC and IAEA emergency alert levels for the public begin at 1 mSv/h; portable radiation survey instruments have a dedicated mSv/h range. 1 mSv/h = 1 mGy/h for photons.
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.
