DAP unit converter for radiology technologist

There are lot of tools to convert units (uGy, nGy, m2, cm2) to your needs, but they are dedicated mostly for all possible units.

There I want to save for me and for you most used units for radiology technologists.

1 mGy.cm2 = 0,0001 mGy.m2

1 mGy.m2 = 10.000 mGy.cm2

Simple example with respect to unit conversions:
When converting from Gy.cm2 to µGy.m2 the following reasoning can be followed: 1 Gy = 1,000,000 (1 million) µGy; 1 cm2 = 0.0001 m2; this means that 1 Gy.cm2 = 1,000,000*0.0001 µGy.m2 = 100 µGy.m2.

1 gray (Gy) = 100 rads 10 mGy = 1 rad 1 mGy = 100 mrad

Other info:
For example, a 5 cm × 5 cm X-ray field with an entrance dose of 1 mGy will yield a 25 mGy·cm² DAP value. When the field is increased to 10 cm × 10 cm with the same entrance dose, the DAP increases to 100 mGy·cm², which is four times the previous value^.
