About Converting Ronnasieverts to Nanosieverts
Ronnasievert and Nanosievert 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: Ronnasievert is 1e+27 sievert units, and nanosievert is 1e-9 sievert units.
Formula
nanosieverts = ronnasieverts × 1e+36
This factor comes from each unit's defined relationship to the category's base unit: 1 ronnasievert equals 1e+27 base units, and 1 nanosievert equals 1e-9 base units, so dividing one by the other gives the direct ronnasievert-to-nanosievert factor of 1e+36.
Simple example
1 RSv × 1e+36 = 1e+36 nSv
1 ronnasievert = 1e+36 nanosieverts.
Real-world example
10 RSv × 1e+36 = 1e+37 nSv
10 ronnasieverts = 1e+37 nanosieverts.

Frequently asked questions
How many nanosieverts are in 1 ronnasievert?
1 ronnasievert equals 1e+36 nanosieverts, using the exact defined conversion factor rather than an estimate.
How do I convert ronnasievert to nanosievert?
Multiply the ronnasievert value by 1e+36. The converter above does this instantly to whatever precision you set.
How do I convert nanosievert back to ronnasievert?
Use the reverse factor: 1 nanosievert equals 1e-36 ronnasieverts. You can also use the swap control in the converter above to flip the direction instantly.
What is a ronnasievert?
Ronnasievert (RSv) is a unit of radiation.
What is a nanosievert?
Nanosievert (nSv) is a unit of radiation.
Is the ronnasievert to nanosievert conversion exact?
Yes. Both ronnasievert and nanosievert are defined by fixed standards rather than physical artifacts, so the factor of 1e+36 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.
