Milligrays (mGy) to Rads (rad) Formula
To convert from Milligrays (mGy) to Rads (rad), use the exact physical definition relationship:
Primary Formula:
rad = mGy / 10 (or rad = mGy × 0.1)
Calculation Examples
- Example 1: 10 mGy = 1 rad
- Example 2: 15 mGy = 1.5 rad (typical abdominal CT scan absorbed dose)
- Example 3: 50 mGy = 5 rad
- Example 4: 100 mGy = 10 rad

Frequently Asked Questions
How many Rads are in 1 Gray?
Exactly 100 Rads. One Gray equals 100 Rads (1 Gy = 100 rad). Conversely, 1 Rad equals 0.01 Grays (1 rad = 0.01 Gy = 10 mGy).
What is the difference between Absorbed Dose (Gy) and Equivalent Dose (Sv)?
Absorbed dose (measured in Grays or rads) quantifies the pure physical energy deposited in matter (1 Gy = 1 J/kg). Equivalent dose (measured in Sieverts or rem) multiplies absorbed dose by a radiation weighting factor (W_R) to reflect the biological severity of specific radiation types (e.g., alpha particles have W_R = 20, whereas photons have W_R = 1).
Why did the Gray replace the Rad in scientific standards?
The International Commission on Radiation Units and Measurements (ICRU) and the General Conference on Weights and Measures (CGPM) adopted the Gray in 1975 to integrate radiation dosimetry directly into the coherent SI metric framework (joules per kilogram), eliminating cumbersome CGS conversion factors.
