1 roentgen=.876rad
This is for Exposure (always in air) to Dose (in rad) in air.
For Dose in other materials, the Roentgen-to-Rad conversion factor (often called f-factor) varies quite a bit.
For example, the f-factor for dose absorption in bone is ~4x higher than the f-factor for absorption of dose in tissue when the energy range is ~ 100 keV.
f-factor = W/e [J/C] *2.58E-4 [C/kg/R]
where
W is Average Energy expended in air per ion pair formed
e is electron charge (1.602E-19 C/ion pair))
and 2.58E-4 [C/kg/R] is a unit conversion from Roentgens to SI units [Coulomb/kilogram].
W varies quite a bit from material to material.

How many rad is 1 cm3?
the old unit of absorbed radiation dose the roentgen is defined as the dose of radiation which produces 2.1x109 ion pairs in 1 cm3 of air. the energy necessary to produce 1 ion pair is eV where 1 eV = 1.6x10-19 J. given that the absorbed dose unit, the rad, is defined as 10-2 J/kg, and the density of air is 1.29x10-3 g/cm3, how many rad is 1 roentgen?
What is the conversion factor for angstrom to nanometers?

What is the conversion factor for 15?
There can be no conversion factor for a single number.
What is the conversion factor of 46.2 yds to meters?
The conversion factor is 0.91
How many rads is 31 roentgens?
To convert roentgens (R) to rad, you typically use the conversion factor of 1 R being approximately equal to 1 rad for gamma and X-ray radiation in air. Therefore, 31 roentgens is approximately 31 rads. However, the exact conversion can vary based on the type of radiation and its energy, so it's important to consider the context in specific situations.

Is a conversion factor written as a fraction?
Not necessarily. The conversion factor from feet to inches is 12.
