How to convert micrograys to grays
One gray is one joule deposited per kilogram; one rad is 0.01 gray. Equivalent dose in sieverts incorporates radiation weighting and belongs to a separate calculator.
Use x for the value in µGy, b for the intermediate value in Gy, and y for the result in Gy.
Gy = µGy × 0.000001
Worked examples
10 µGy ≈ 0.00001 Gy
Step 1: (10 × 0.000001) ≈ 0.00001 Gy.
Step 2: 0.00001 ÷ 1 ≈ 0.00001 Gy.20 µGy ≈ 0.00002 Gy
Step 1: (20 × 0.000001) ≈ 0.00002 Gy.
Step 2: 0.00002 ÷ 1 ≈ 0.00002 Gy.
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 Micrograys
Micrograys (µGy) measures radiation absorbed dose under the conventions above. The base value in Gy is (x × 0.000001), where x is the numerical value in µGy. Factors shown here are rounded for display; calculations use the stored factor.
About Grays
Grays (Gy) measures radiation absorbed dose under the conventions above. The base value in Gy is (x × 1), where x is the numerical value in Gy. Factors shown here are rounded for display; calculations use the stored factor.
