About this calculator
This calculator converts radiation doses measured in Sieverts (Sv) to rem, the unit commonly used in clinical radiology and radiation protection. The resulting value allows professionals to compare exposures with safety limits expressed in rem.
The conversion is straightforward: multiply the Sievert value by one hundred. This is because one Sv equals one hundred rem. The tool performs the calculation in milliseconds and displays the result instantly.
Use it when you need to convert results from CT scans or dosimetry reports that return in Sv to rem, or when comparing doses with Brazilian regulations that use rem. It is useful for doctors, radiology technicians, safety engineers, and public health professionals.
Caution: the calculator provides only a numeric conversion. It does not replace risk assessment, biological weighting factors or protection protocols. For critical exposures, consult a radiation protection specialist.
Frequently asked questions
What are Sievert and rem?
Sievert measures effective radiation dose, accounting for biological effect. Rem is an older unit of equivalent dose, with 1 Sv equal to 100 rem.
Why convert Sv to rem?
Many Brazilian safety regulations use rem, so conversion makes it easier to compare with national limits.
Does the calculator account for biological weighting factors?
No, it simply multiplies by 100. Weighting factors are applied in dose calculations before conversion.
How long does it take to get the result?
The calculation is instant; the result appears in milliseconds.
Can I use it for cumulative exposures from multiple exams?
Yes, sum the doses in Sv first and then convert. Remember to add before multiplying by 100.
