About Converting Petasieverts to Exasieverts
Petasievert and Exasievert 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: Petasievert is 1000000000000000 sievert units, and exasievert is 1000000000000000000 sievert units.
Formula
exasieverts = petasieverts × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 petasievert equals 1e+15 base units, and 1 exasievert equals 1e+18 base units, so dividing one by the other gives the direct petasievert-to-exasievert factor of 0.001.
Simple example
1 PSv × 0.001 = 0.001 ESv
1 petasievert = 0.001 exasieverts.
Real-world example
10 PSv × 0.001 = 0.01 ESv
10 petasieverts = 0.01 exasieverts.

Frequently asked questions
How many exasieverts are in 1 petasievert?
1 petasievert equals 0.001 exasieverts, using the exact defined conversion factor rather than an estimate.
How do I convert petasievert to exasievert?
Multiply the petasievert value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert exasievert back to petasievert?
Use the reverse factor: 1 exasievert equals 1,000 petasieverts. You can also use the swap control in the converter above to flip the direction instantly.
What is a petasievert?
Petasievert (PSv) is a unit of radiation.
What is a exasievert?
Exasievert (ESv) is a unit of radiation.
Is the petasievert to exasievert conversion exact?
Yes. Both petasievert and exasievert are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
