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

Reverse conversion: Microsievert to Picosievert
0.000001 uSv × 1000000 = 1 pSv
0.000001 microsieverts = 1 picosievert.
picosieverts = microsieverts × 1000000

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