About Converting Petasieverts to Terasieverts
Petasievert and Terasievert 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 terasievert is 1000000000000 sievert units.
Formula
terasieverts = petasieverts × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 petasievert equals 1e+15 base units, and 1 terasievert equals 1e+12 base units, so dividing one by the other gives the direct petasievert-to-terasievert factor of 1000.
Simple example
1 PSv × 1000 = 1,000 TSv
1 petasievert = 1,000 terasieverts.
Real-world example
10 PSv × 1000 = 10,000 TSv
10 petasieverts = 10,000 terasieverts.

Frequently asked questions
How many terasieverts are in 1 petasievert?
1 petasievert equals 1,000 terasieverts, using the exact defined conversion factor rather than an estimate.
How do I convert petasievert to terasievert?
Multiply the petasievert value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert terasievert back to petasievert?
Use the reverse factor: 1 terasievert equals 0.001 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 terasievert?
Terasievert (TSv) is a unit of radiation.
Is the petasievert to terasievert conversion exact?
Yes. Both petasievert and terasievert are defined by fixed standards rather than physical artifacts, so the factor of 1000 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.
