How to convert grays per second to milligrays per hour
mGy/h = Gy/s × 3,600,000Multiply the value in grays per second by 3,600,000. To go the other way, multiply by 2.777777778×10⁻⁷ (or divide by 3,600,000).
A gray per second is larger than a milligray per hour: one gray per second contains 3,600,000 milligrays per hour.

About the units
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).
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).
Frequently asked questions
How many milligrays per hour are in one gray per second?
There are 3,600,000 milligrays per hour in one gray per second, and this value is exact by definition.
How do I convert grays per second to milligrays per hour?
Multiply the number of grays per second by 3,600,000. For example, 10 Gy/s × 3,600,000 = 36,000,000 mGy/h.
How many grays per second are in one milligray per hour?
One milligray per hour equals 2.777777778×10⁻⁷ grays per second. That is the reverse factor, 1 ÷ 3,600,000.
What is 10 grays per second in milligrays per hour?
10 Gy/s = 36,000,000 mGy/h.
Is this Gy/s to mGy/h converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
