How to Convert Rads to Millirem
The rad and millirem are both units of radiation dose. By definition, 1 rad equals exactly 1000 millirem. This means to convert rads to millirem, you multiply by 1000.
Formula
Step-by-Step Example
Convert 5 rad to millirem:
We need to convert rads to millirem
Since 1 rad = 1000 mrem, multiply by 1000
5 × 1000 = 5000
5 rad = 5000 mrem

About These Units
Rad (rad)
The rad (Radiation Absorbed Dose) is the traditional unit of absorbed dose. One gray = 100 rads exactly. One rad = 100 ergs/gram = 0.01 J/kg. Still used in US medical and nuclear industries. One rad = one centigray = one rem for gamma/X-rays.
Millirem (mrem)
A millirem (mrem) equals 0.001 rem or 10 μSv. US dosimetry standard: natural background 300-400 mrem/year, occupational limit 5,000 mrem/year, public limit 100 mrem/year above background. Chest X-ray: ~2 mrem.
