About Converting Centisieverts to Millisieverts
Centisievert and Millisievert 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: Centisievert is 0.01 sievert units, and millisievert is 0.001 sievert units.
Formula
millisieverts = centisieverts × 10
This factor comes from each unit's defined relationship to the category's base unit: 1 centisievert equals 0.01 base units, and 1 millisievert equals 0.001 base units, so dividing one by the other gives the direct centisievert-to-millisievert factor of 10.
Simple example
1 cSv × 10 = 10 mSv
1 centisievert = 10 millisieverts.
Real-world example
10 cSv × 10 = 100 mSv
10 centisieverts = 100 millisieverts.

Frequently asked questions
How many millisieverts are in 1 centisievert?
1 centisievert equals 10 millisieverts, using the exact defined conversion factor rather than an estimate.
How do I convert centisievert to millisievert?
Multiply the centisievert value by 10. The converter above does this instantly to whatever precision you set.
How do I convert millisievert back to centisievert?
Use the reverse factor: 1 millisievert equals 0.1 centisieverts. You can also use the swap control in the converter above to flip the direction instantly.
What is a centisievert?
Centisievert (cSv) is a unit of radiation.
What is a millisievert?
Millisievert (mSv) is a unit of radiation.
Is the centisievert to millisievert conversion exact?
Yes. Both centisievert and millisievert are defined by fixed standards rather than physical artifacts, so the factor of 10 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.
