decisievert to attosievert
Convert decisievert (dSv) to attosievert (aSv). Use an editable equivalent dose converter, conversion formula, and reference table.
1 dSv = 1e+17 aSv
Conversion formula
One decisievert equals 1e+17 attosievert. Multiply your value in decisievert by this factor to get attosievert. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 decisievert:5 × 1e+17 = 5e+17 aSv

About these measurements
Equivalent dose uses weighting to describe radiation-related biological effects.
The base reference used here is the sievert. One decisievert is 0.1 base units; one attosievert is 1e-18 base units.
Important distinctions
This converts an already specified quantity. It does not calculate a personal risk or treatment.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
