About Converting Microsieverts to Decisieverts
Microsievert and Decisievert 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: Microsievert is 0.000001 sievert units, and decisievert is 0.1 sievert units.
Formula
decisieverts = microsieverts × 0.00001
This factor comes from each unit's defined relationship to the category's base unit: 1 microsievert equals 0.000001 base units, and 1 decisievert equals 0.1 base units, so dividing one by the other gives the direct microsievert-to-decisievert factor of 0.00001.
Simple example
1 uSv × 0.00001 = 0.00001 dSv
1 microsievert = 0.00001 decisieverts.
Real-world example
10 uSv × 0.00001 = 0.0001 dSv
10 microsieverts = 0.0001 decisieverts.

Reverse conversion: Decisievert to Microsievert
0.00001 dSv × 100000 = 1 uSv
0.00001 decisieverts = 1 microsieverts.
microsieverts = decisieverts × 100000

Frequently asked questions
How many decisieverts are in 1 microsievert?
1 microsievert equals 0.00001 decisieverts, using the exact defined conversion factor rather than an estimate.
How do I convert microsievert to decisievert?
Multiply the microsievert value by 0.00001. The converter above does this instantly to whatever precision you set.
How do I convert decisievert back to microsievert?
Use the reverse factor: 1 decisievert equals 100,000 microsieverts. You can also use the swap control in the converter above to flip the direction instantly.
What is a microsievert?
Microsievert (uSv) is a unit of radiation.
What is a decisievert?
Decisievert (dSv) is a unit of radiation.
Is the microsievert to decisievert conversion exact?
Yes. Both microsievert and decisievert are defined by fixed standards rather than physical artifacts, so the factor of 0.00001 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.
