About Converting Megasieverts to Centisieverts
Megasievert 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: Megasievert is 1000000 sievert units, and centisievert is 0.01 sievert units.
Formula
centisieverts = megasieverts × 100000000
This factor comes from each unit's defined relationship to the category's base unit: 1 megasievert equals 1000000 base units, and 1 centisievert equals 0.01 base units, so dividing one by the other gives the direct megasievert-to-centisievert factor of 100000000.
Simple example
1 MSv × 100000000 = 100,000,000 cSv
1 megasievert = 100,000,000 centisieverts.
Real-world example
10 MSv × 100000000 = 1,000,000,000 cSv
10 megasieverts = 1,000,000,000 centisieverts.

Reverse conversion: Centisievert to Megasievert
1 cSv × 1e-8 = 1e-8 MSv
1 centisievert = 1e-8 megasieverts.
megasieverts = centisieverts × 1e-8

Frequently asked questions
How many centisieverts are in 1 megasievert?
1 megasievert equals 100,000,000 centisieverts, using the exact defined conversion factor rather than an estimate.
How do I convert megasievert to centisievert?
Multiply the megasievert value by 100000000. The converter above does this instantly to whatever precision you set.
How do I convert centisievert back to megasievert?
Use the reverse factor: 1 centisievert equals 1e-8 megasieverts. You can also use the swap control in the converter above to flip the direction instantly.
What is a megasievert?
Megasievert (MSv) is a unit of radiation.
What is a centisievert?
Centisievert (cSv) is a unit of radiation.
Is the megasievert to centisievert conversion exact?
Yes. Both megasievert and centisievert are defined by fixed standards rather than physical artifacts, so the factor of 100000000 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.
