About Converting Gigasieverts to Petasieverts
Gigasievert and Petasievert 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: Gigasievert is 1000000000 sievert units, and petasievert is 1000000000000000 sievert units.
Formula
petasieverts = gigasieverts × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 gigasievert equals 1000000000 base units, and 1 petasievert equals 1e+15 base units, so dividing one by the other gives the direct gigasievert-to-petasievert factor of 0.000001.
Simple example
1 GSv × 0.000001 = 0.000001 PSv
1 gigasievert = 0.000001 petasieverts.
Real-world example
10 GSv × 0.000001 = 0.00001 PSv
10 gigasieverts = 0.00001 petasieverts.

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