rem to hectosievert
Convert rem (rem) to hectosievert (hSv). Use an editable equivalent dose converter, conversion formula, and reference table.
1 rem = 0.0001 hSv
Conversion formula
One rem equals 0.0001 hectosievert. Multiply your value in rem by this factor to get hectosievert. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 rem:5 × 0.0001 = 0.0005 hSv

About these measurements
Equivalent dose uses weighting to describe radiation-related biological effects.
The base reference used here is the sievert. One rem is 0.01 base units; one hectosievert is 100 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 rem to hSv?
Multiply the quantity in rem by 0.0001. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the hectosievert to rem converter.
