About Converting Attosieverts to Centisieverts
Attosievert and Centisievert both belong to the radiation-measurement family, though radiation quantities fall into genuinely distinct categories: absorbed dose (gray, rad) measures energy deposited in matter, equivalent dose (sievert, rem) weights that for biological harm, and activity (becquerel, curie) measures how often a radioactive source decays — this page only converts between units of the same kind. Specifically: Attosievert is 1e-18 sievert units, and centisievert is 0.01 sievert units.
Formula
centisieverts = attosieverts × 1e-16
This factor comes from each unit's defined relationship to the category's base unit: 1 attosievert equals 1e-18 base units, and 1 centisievert equals 0.01 base units, so dividing one by the other gives the direct attosievert-to-centisievert factor of 1e-16.
Simple example
1 aSv × 1e-16 = 1e-16 cSv
1 attosievert = 1e-16 centisieverts.
Real-world example
10 aSv × 1e-16 = 1e-15 cSv
10 attosieverts = 1e-15 centisieverts.

Reverse conversion: Centisievert to Attosievert
1e-16 cSv × 1e+16 = 1 aSv
1e-16 centisieverts = 1 attosievert.
attosieverts = centisieverts × 1e+16

Frequently asked questions
How many centisieverts are in 1 attosievert?
1 attosievert equals 1e-16 centisieverts, using the exact defined conversion factor rather than an estimate.
How do I convert attosievert to centisievert?
Multiply the attosievert value by 1e-16. The converter above does this instantly to whatever precision you set.
How do I convert centisievert back to attosievert?
Use the reverse factor: 1 centisievert equals 1e+16 attosieverts. You can also use the swap control in the converter above to flip the direction instantly.
What is a attosievert?
Attosievert (aSv) is a unit of radiation.
What is a centisievert?
Centisievert (cSv) is a unit of radiation.
Is the attosievert to centisievert conversion exact?
Yes. Both attosievert and centisievert are defined by fixed standards rather than physical artifacts, so the factor of 1e-16 used above is exact to as many digits as you choose to display.
What's the difference between absorbed dose, equivalent dose, and activity?
Absorbed dose (gray, rad) measures the energy radiation deposits in matter. Equivalent dose (sievert, rem) adjusts that figure for how harmful different types of radiation are to biological tissue. Activity (becquerel, curie) measures how often a radioactive source decays, independent of how much dose a person actually receives from it.
