Use the Radiation Absorbed Dose Converter
Radiation Absorbed Dose formula and what each symbol means
target = value × (factor of starting unit ÷ factor of target unit), where each factor is the unit value in Gy.
| Symbol | Meaning |
|---|---|
| value | The number you want to convert |
| factor | The unit’s size expressed in the base unit (Gy) |

How to read your Radiation Absorbed Dose result
Absorbed dose is energy deposited per unit mass. The SI unit is the gray, one joule per kilogram. One rad is exactly 0.01 Gy, so 1 Gy is 100 rad.
| UNIT | SYMBOL | EQUALS | VALUE OF 1 GY |
|---|---|---|---|
| Gray | Gy | 1 Gy = 1 Gy | 1 Gy |
| Milligray | mGy | 1 mGy = 0.001 Gy | 1,000 mGy |
| Microgray | µGy | 1 µGy = 0.000001 Gy | 1,000,000 µGy |
| Rad | rad | 1 rad = 0.01 Gy | 100 rad |
| Millirad | mrad | 1 mrad = 0.00001 Gy | 100,000 mrad |
| Joule per kilogram | J/kg | 1 J/kg = 1 Gy | 1 J/kg |
| Erg per gram | erg/g | 1 erg/g = 0.0001 Gy | 10,000 erg/g |
Common mistakes when calculating Radiation Absorbed Dose
- Confusing absorbed dose (Gy) with dose equivalent (Sv).
- Mixing mGy and µGy, which differ by 1,000.
- Mixing rad (dose) with rem (dose equivalent).
Radiation Absorbed Dose FAQ
How many rad is 1 Gy?
1 Gy is 100 rad.
How many Gy is 1 rad?
Exactly 0.01 Gy.
What is a gray?
One joule of energy absorbed per kilogram of matter.
What is the base unit for radiation absorbed dose?
This converter uses gray (Gy) as the common base unit: every value is first converted to it and then to the target unit.
How do I convert between two radiation absorbed dose units?
Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.
How many milligrays are in 1 gray?
1 Gy = 1,000 mGy.
How many rads are in 1 gray?
1 Gy = 100 rad.
How many micrograys are in 1 gray?
1 Gy = 1,000,000 µGy.
Which radiation absorbed dose units does this converter support?
It covers 7 units: gray (Gy), milligray (mGy), microgray (µGy), rad (rad), millirad (mrad), joule per kilogram (J/kg), erg per gram (erg/g).
How accurate is the radiation absorbed dose converter?
Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
