There is no point reaching for a calculator that cannot show its working. This one starts from dose in milligrays and dose in millisieverts and reports dose equivalent in roentgen equivalent man (rem), dose in microsieverts and dose in grays, so you can see how each answer follows from the numbers you entered.
What Is the Radiation Converter Calculator?
The radiation converter calculator converts dose in milligrays and dose in millisieverts between the units you need, so you do not have to hunt for a factor and work it out longhand.
Conversion factors are where unit mistakes happen, and a mistake here tends to propagate silently into everything calculated from it afterwards.
How the Radiation Converter Conversion Works
Each conversion uses the exact factor defined for the unit, so the answer is right to the precision you would normally quote.
Convert at one end rather than at several. Converting to a common unit first and then back again introduces rounding that you then have to carry through the rest of the calculation.
Getting the Units Right
Check that the unit you are converting from is the unit you actually measured in. Similar-looking units, particularly gallons and litres or ounces and grams, are the usual source of a factor-of-ten error.
Write down both the value and its unit. A number without a unit is not a measurement, it is a guess.
A Worked Example
Working through an example, with dose in milligrays set to 10, dose in millisieverts set to 5, the calculator returns dose in grays of 10, and dose in rads of 10, and dose in microsieverts of 5. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out dose equivalent in roentgen equivalent man (rem)?
Enter dose in milligrays and dose in millisieverts. The calculator then works through the relationship and reports dose equivalent in roentgen equivalent man (rem), dose in microsieverts and dose in grays.
What does the radiation converter actually calculate?
It takes dose in milligrays and dose in millisieverts and converts them into dose equivalent in roentgen equivalent man (rem), dose in microsieverts and dose in grays using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter dose in milligrays?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Why does a small change in one value move the answer so much?
That happens when an output depends on a ratio, because dividing by a small number magnifies any change in it. Check the units first, then check whether the value you entered is in the range the relationship was designed for.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
