Convert Milligrays per second to Nanograys per hour
Convert Milligrays per second (mGy/s) to Nanograys per hour (nGy/h) instantly and accurately.
Conversion Formula
nGy/h = mGy/s × 3600000000
About Milligrays per second
The milligray per second (mGy/s) equals 1e-3 Gy/s. Used in high-dose-rate applications: medical linac output in IMRT mode is 1-5 mGy/s at isocentre; electron beam processing conveyors deliver 1-10 mGy/s; real-time diode dosimeters in linac vaults measure instantaneous dose rate in mGy/s during beam-on periods. 1 mGy/s = 0.1 rad/s = 3.6 Gy/h.
About Nanograys per hour
The nanogray per hour (nGy/h) equals 1e-9 Gy/h ≈ 2.78×10⁻¹³ Gy/s. Natural background cosmic-ray dose rates at sea level are 30-50 nGy/h; at aviation cruising altitude they rise to 3000-6000 nGy/h. IAEA environmental surveillance networks and national monitoring stations report ambient gamma dose rates in nGy/h. 1 nGy/h = 1e-9 Gy/h.
