It is not practical, nor is it important, for the public to be able to convert from decirisk to probability. You can use our calculator to work out the decirisk if you know the probability.
Since most people do not understand probability, decirisk has far more meaning and will be the main conceptual tool of risk comparison.

The important point is that the bigger the decirisk, the bigger the actual risk. Understanding decirisk is a little like understanding a percentage. It is a matter of getting a feeling for it.

Therefore a standard scale of decirisks should be presented for comparison.
The following decirisks have been rounded to the nearest whole number.
