About Converting Millisieverts to Centisieverts
Millisievert and Centisievert 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: Millisievert is 0.001 sievert units, and centisievert is 0.01 sievert units.
Formula
centisieverts = millisieverts × 0.1
This factor comes from each unit's defined relationship to the category's base unit: 1 millisievert equals 0.001 base units, and 1 centisievert equals 0.01 base units, so dividing one by the other gives the direct millisievert-to-centisievert factor of 0.1.
Simple example
1 mSv × 0.1 = 0.1 cSv
1 millisievert = 0.1 centisieverts.
Real-world example
10 mSv × 0.1 = 1 cSv
10 millisieverts = 1 centisievert.

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