Radiation Absorbed Dose / rad → µGy
Convert Rads to Micrograys
Convert absorbed ionizing-radiation energy per mass in grays and rads. Convert Rads (rad) to Micrograys (µGy). Find the formula, worked examples, unit definitions, and practical guidance below.
How to convert rads to micrograys
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 rad, b for the intermediate value in Gy, and y for the result in µGy.
µGy = rad × 0.01 ÷ 0.000001
Worked examples
10 rad ≈ 100000 µGy
Step 1: (10 × 0.01) ≈ 0.1 Gy.
Step 2: 0.1 ÷ 0.000001 ≈ 100000 µGy.20 rad ≈ 200000 µGy
Step 1: (20 × 0.01) ≈ 0.2 Gy.
Step 2: 0.2 ÷ 0.000001 ≈ 200000 µGy.
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 Rads
Rads (rad) measures radiation absorbed dose under the conventions above. The base value in Gy is (x × 0.01), where x is the numerical value in rad. Factors shown here are rounded for display; calculations use the stored factor.
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.
