How to convert milligrays per hour to grays per second
Gy/s = mGy/h × 2.777777778×10⁻⁷Because one gray per second equals 3,600,000 milligrays per hour, you can also divide: Gy/s = mGy/h ÷ 3,600,000.
A milligray per hour is smaller than a gray per second: it takes 3,600,000 milligrays per hour to make one gray per second.

About the units
Milligray per hour (mGy/h)
The milligray per hour (mGy/h) is a unit of radiation (absorbed dose rate) in the International System of Units (SI). One milligray per hour equals 2.777777778×10⁻⁷ grays per second (Gy/s).
Gray per second (Gy/s)
The gray per second (Gy/s) is a unit of radiation (absorbed dose rate) in the International System of Units (SI).
Frequently asked questions
How many grays per second are in one milligray per hour?
There are 2.777777778×10⁻⁷ grays per second in one milligray per hour, and this value is exact by definition.
How do I convert milligrays per hour to grays per second?
Multiply the number of milligrays per hour by 2.777777778×10⁻⁷. For example, 10 mGy/h × 2.777777778×10⁻⁷ = 0.000002777777778 Gy/s.
How many milligrays per hour are in one gray per second?
One gray per second equals 3,600,000 milligrays per hour. That is the reverse factor, 1 ÷ 2.777777778×10⁻⁷.
What is 10 milligrays per hour in grays per second?
10 mGy/h = 0.000002777777778 Gy/s.
