How to convert milligrays per hour to grays per second
Radiation here means absorbed-dose rate in Gy/s. It is not radioactivity, exposure, or equivalent-dose rate. Sieverts per time require radiation weighting and cannot be equated to grays per time.
Use x for the value in mGy/h, b for the intermediate value in Gy/s, and y for the result in Gy/s.
Gy/s = mGy/h × 2.7777777777777776e-7
Worked examples
10 mGy/h ≈ 0.00000277777777778 Gy/s
Step 1: (10 × 2.77777777778e-7) ≈ 0.00000277777777778 Gy/s.
Step 2: 0.00000277777777778 ÷ 1 ≈ 0.00000277777777778 Gy/s.20 mGy/h ≈ 0.00000555555555556 Gy/s
Step 1: (20 × 2.77777777778e-7) ≈ 0.00000555555555556 Gy/s.
Step 2: 0.00000555555555556 ÷ 1 ≈ 0.00000555555555556 Gy/s.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Milligrays per hour
Milligrays per hour (mGy/h) measures radiation under the conventions above. The base value in Gy/s is (x × 2.77777777778e-7), where x is the numerical value in mGy/h. Factors shown here are rounded for display; calculations use the stored factor.
About Grays per second
Grays per second (Gy/s) measures radiation under the conventions above. The base value in Gy/s is (x × 1), where x is the numerical value in Gy/s. Factors shown here are rounded for display; calculations use the stored factor.
