Convert rad to femtogray

The rad na the CGS unit of absorbed radiation dose, equal to the absorption of 100 ergs of energy per gram of matter (0.01 grays).

The femtogray equal to 10⁻¹⁵ grays, used in theoretical radiation biophysics.

1 rd = 1E+13 fGy. To convert any value, multiply it by 1E+13. For example, 25 rd = 2.5E+14 fGy.

How many fGy are there in one rd?: One rd is equal to 1E+13 fGy.
How do you convert Rad to Femtogray?: Multiply the value in Rad by 1E+13 to get the result in Femtogray.
How much is 25 rd in fGy?: 25 rd is equal to 2.5E+14 fGy.
How do you convert Femtogray back to Rad?: Divide by the same factor: multiply the value in Femtogray by 1E-13 to get Rad.
