microsievert to nanosievert
Convert microsievert (μSv) to nanosievert (nSv). Use an editable equivalent dose converter, conversion formula, and reference table.
1 μSv = 1,000 nSv
Conversion formula
One microsievert equals 1,000 nanosievert. Multiply your value in microsievert by this factor to get nanosievert. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 microsievert:5 × 1,000 = 5,000 nSv

About these measurements
Equivalent dose uses weighting to describe radiation-related biological effects.
The base reference used here is the sievert. One microsievert is 0.000001 base units; one nanosievert is 1e-9 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 μSv to nSv?
Multiply the quantity in μSv 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 nanosievert to microsievert converter.
