About Converting Picosieverts to Attosieverts
Picosievert and Attosievert 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: Picosievert is 1e-12 sievert units, and attosievert is 1e-18 sievert units.
Formula
attosieverts = picosieverts × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 picosievert equals 1e-12 base units, and 1 attosievert equals 1e-18 base units, so dividing one by the other gives the direct picosievert-to-attosievert factor of 1000000.
Simple example
1 pSv × 1000000 = 1,000,000 aSv
1 picosievert = 1,000,000 attosieverts.
Real-world example
10 pSv × 1000000 = 10,000,000 aSv
10 picosieverts = 10,000,000 attosieverts.

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

Frequently asked questions
How many attosieverts are in 1 picosievert?
1 picosievert equals 1,000,000 attosieverts, using the exact defined conversion factor rather than an estimate.
How do I convert picosievert to attosievert?
Multiply the picosievert value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert attosievert back to picosievert?
Use the reverse factor: 1 attosievert equals 0.000001 picosieverts. You can also use the swap control in the converter above to flip the direction instantly.
What is a picosievert?
Picosievert (pSv) is a unit of radiation.
What is a attosievert?
Attosievert (aSv) is a unit of radiation.
Is the picosievert to attosievert conversion exact?
Yes. Both picosievert and attosievert are defined by fixed standards rather than physical artifacts, so the factor of 1000000 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.
