About Converting Attosieverts to Picosieverts
Attosievert and Picosievert 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 picosievert is 1e-12 sievert units.
Formula
picosieverts = attosieverts × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 attosievert equals 1e-18 base units, and 1 picosievert equals 1e-12 base units, so dividing one by the other gives the direct attosievert-to-picosievert factor of 0.000001.
Simple example
1 aSv × 0.000001 = 0.000001 pSv
1 attosievert = 0.000001 picosieverts.
Real-world example
10 aSv × 0.000001 = 0.00001 pSv
10 attosieverts = 0.00001 picosieverts.

Reverse conversion: Picosievert to Attosievert
0.000001 pSv × 1000000 = 1 aSv
0.000001 picosieverts = 1 attosieverts.
attosieverts = picosieverts × 1000000

Frequently asked questions
How many picosieverts are in 1 attosievert?
1 attosievert equals 0.000001 picosieverts, using the exact defined conversion factor rather than an estimate.
How do I convert attosievert to picosievert?
Multiply the attosievert value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert picosievert back to attosievert?
Use the reverse factor: 1 picosievert equals 1,000,000 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 picosievert?
Picosievert (pSv) is a unit of radiation.
Is the attosievert to picosievert conversion exact?
Yes. Both attosievert and picosievert are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
