Convert Nanograys per hour to Grays per hour

Convert Nanograys per hour (nGy/h) to Grays per hour (Gy/h) instantly and accurately.

Nanograys per hour (nGy/h)
Grays per hour (Gy/h)

Conversion Formula

Gy/h = nGy/h × 1.000000000e-9

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.

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.
