About Converting Kilosieverts to Gigasieverts
Kilosievert 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: Kilosievert is 1000 sievert units, and gigasievert is 1000000000 sievert units.
Formula
gigasieverts = kilosieverts × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 kilosievert equals 1000 base units, and 1 gigasievert equals 1000000000 base units, so dividing one by the other gives the direct kilosievert-to-gigasievert factor of 0.000001.
Simple example
1 kSv × 0.000001 = 0.000001 GSv
1 kilosievert = 0.000001 gigasieverts.
Real-world example
10 kSv × 0.000001 = 0.00001 GSv
10 kilosieverts = 0.00001 gigasieverts.

Reverse conversion: Gigasievert to Kilosievert
0.000001 GSv × 1000000 = 1 kSv
0.000001 gigasieverts = 1 kilosievert.
kilosieverts = gigasieverts × 1000000

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