Convert Microsieverts per hour (µSv/h) to Nanograys per hour (nGy/h) instantly and accurately.

Microsieverts per hour (µSv/h)
Nanograys per hour (nGy/h)

Conversion Formula

nGy/h = µSv/h × 1000

About Microsieverts per hour

The microsievert per hour (µSv/h) equals 1e-6 Sv/h = 1e-6 Gy/h for photon radiation (wR = 1). The universal display unit of personal electronic dosimeters and ambient dose-equivalent rate monitors: typical outdoor background 0.08-0.3 µSv/h; IAEA precautionary action level is 100 µSv/h; occupational continuous limit ≈2.3 µSv/h. 1 µSv/h = 1 µGy/h for photons.

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.
