Convert femtogray to rad

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

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).

1 fGy = 1E-13 rd. To convert any value, multiply it by 1E-13. For example, 25 fGy = 2.5E-12 rd.

How many rd are there in one fGy?: One fGy is equal to 1E-13 rd.
How do you convert Femtogray to Rad?: Multiply the value in Femtogray by 1E-13 to get the result in Rad.
How much is 25 fGy in rd?: 25 fGy is equal to 2.5E-12 rd.
How do you convert Rad back to Femtogray?: Divide by the same factor: multiply the value in Rad by 1E+13 to get Femtogray.
