millisievert to kilosievert
Convert millisievert (mSv) to kilosievert (kSv). Use an editable equivalent dose converter, conversion formula, and reference table.
1 mSv = 0.000001 kSv
Conversion formula
One millisievert equals 0.000001 kilosievert. Multiply your value in millisievert by this factor to get kilosievert. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 millisievert:5 × 0.000001 = 0.000005 kSv

About these measurements
Equivalent dose uses weighting to describe radiation-related biological effects.
The base reference used here is the sievert. One millisievert is 0.001 base units; one kilosievert is 1,000 base units.
Important distinctions
This converts an already specified quantity. It does not calculate a personal risk or treatment.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert mSv to kSv?
Multiply the quantity in mSv by 0.000001. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the kilosievert to millisievert converter.
