Millicoulomb per kilogram quick reference
| Millicoulomb per kilogram | Coulomb per kilogram | Roentgen | Milliroentgen |
|---|---|---|---|
| 1 mC/kg | = 0.001 C/kg | ≈ 3.875968992 R | ≈ 3875.968992 mR |
| 10 mC/kg | = 0.01 C/kg | ≈ 38.75968992 R | ≈ 38759.68992 mR |
| 100 mC/kg | = 0.1 C/kg | ≈ 387.5968992 R | ≈ 387596.8992 mR |
| 1000 mC/kg | = 1 C/kg | ≈ 3875.968992 R | ≈ 3875968.992 mR |
Where the millicoulomb per kilogram fits
The next smaller radiation exposure unit is the roentgen (R). 1 mC/kg ≈ 3.875968992 R, and 1 R = 0.258 mC/kg.
The next larger radiation exposure unit is the coulomb per kilogram (C/kg). 1 mC/kg = 0.001 C/kg, and 1 C/kg = 1000 mC/kg.
