How to convert grays per second to grays per hour
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 Gy/s, b for the intermediate value in Gy/s, and y for the result in Gy/h.
Gy/h = Gy/s ÷ 0.0002777777777777778
Worked examples
10 Gy/s ≈ 36000 Gy/h
Step 1: (10 × 1) ≈ 10 Gy/s.
Step 2: 10 ÷ 0.000277777777778 ≈ 36000 Gy/h.20 Gy/s ≈ 72000 Gy/h
Step 1: (20 × 1) ≈ 20 Gy/s.
Step 2: 20 ÷ 0.000277777777778 ≈ 72000 Gy/h.
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 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.
About Grays per hour
Grays per hour (Gy/h) measures radiation under the conventions above. The base value in Gy/s is (x × 0.000277777777778), where x is the numerical value in Gy/h. Factors shown here are rounded for display; calculations use the stored factor.
