About Converting Microsieverts to Picosieverts
Microsievert 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: Microsievert is 0.000001 sievert units, and picosievert is 1e-12 sievert units.
Formula
picosieverts = microsieverts × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 microsievert equals 0.000001 base units, and 1 picosievert equals 1e-12 base units, so dividing one by the other gives the direct microsievert-to-picosievert factor of 1000000.
Simple example
1 uSv × 1000000 = 1,000,000 pSv
1 microsievert = 1,000,000 picosieverts.
Real-world example
10 uSv × 1000000 = 10,000,000 pSv
10 microsieverts = 10,000,000 picosieverts.

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

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