1 mSv = 1,000 μSv

Calculated in your browser

Conversion formula

μSv = mSv × 1,000

One millisievert equals 1,000 microsievert. Multiply your value in millisievert by this factor to get microsievert. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 millisievert:
5 × 1,000 = 5,000 μSv

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 microsievert is 0.000001 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 μSv?

Multiply the quantity in mSv by 1,000. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the microsievert to millisievert converter.
