About Converting Petasieverts to Gigasieverts
Petasievert and Gigasievert 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 gigasievert is 1000000000 sievert units.
Formula
gigasieverts = petasieverts × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 petasievert equals 1e+15 base units, and 1 gigasievert equals 1000000000 base units, so dividing one by the other gives the direct petasievert-to-gigasievert factor of 1000000.
Simple example
1 PSv × 1000000 = 1,000,000 GSv
1 petasievert = 1,000,000 gigasieverts.
Real-world example
10 PSv × 1000000 = 10,000,000 GSv
10 petasieverts = 10,000,000 gigasieverts.

Frequently asked questions
How many gigasieverts are in 1 petasievert?
1 petasievert equals 1,000,000 gigasieverts, using the exact defined conversion factor rather than an estimate.
How do I convert petasievert to gigasievert?
Multiply the petasievert value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert gigasievert back to petasievert?
Use the reverse factor: 1 gigasievert equals 0.000001 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 gigasievert?
Gigasievert (GSv) is a unit of radiation.
Is the petasievert to gigasievert conversion exact?
Yes. Both petasievert and gigasievert 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.
