## Description: Radiation-Absorbed Dose Unit Converter

The Radiation-Absorbed Dose Unit Converter is a tool designed to assist in the conversion between various units used to measure the amount of energy deposited by ionizing radiation in a material. This converter enables seamless transition between different units of absorbed dose, facilitating calculations and comparisons in radiation therapy, radiology, and nuclear medicine.

**Units Explanation:**

**Rad [rd]:**Radiation absorbed dose expressed in rads, where one rad represents the absorption of one hundred ergs of energy per gram of matter.**Millirad [mrd]:**Radiation absorbed dose expressed in millirads, equal to one thousandth of a rad.**Joule/kilogram [J/kg]:**Radiation absorbed dose expressed in joules per kilogram, representing the energy absorbed per unit mass.**Joule/gram [J/g]:**Radiation absorbed dose expressed in joules per gram, representing the energy absorbed per unit mass.**Joule/centigram [J/cg]:**Radiation absorbed dose expressed in joules per centigram, representing the energy absorbed per unit mass.**Joule/milligram [J/mg]:**Radiation absorbed dose expressed in joules per milligram, representing the energy absorbed per unit mass.**Gray [Gy]:**Radiation absorbed dose expressed in grays, where one gray represents the absorption of one joule of radiation energy per kilogram of matter.**Exagray [EGy]:**Radiation absorbed dose expressed in exagrays, equal to one quintillion grays.**Petagray [PGy]:**Radiation absorbed dose expressed in petagrays, equal to one quadrillion grays.**Teragray [TGy]:**Radiation absorbed dose expressed in teragrays, equal to one trillion grays.**Gigagray [GGy]:**Radiation absorbed dose expressed in gigagrays, equal to one billion grays.**Megagray [MGy]:**Radiation absorbed dose expressed in megagrays, equal to one million grays.**Kilogray [kGy]:**Radiation absorbed dose expressed in kilograys, equal to one thousand grays.**Hectogray [hGy]:**Radiation absorbed dose expressed in hectograys, equal to one hundred grays.**Dekagray [daGy]:**Radiation absorbed dose expressed in dekagrays, equal to ten grays.**Decigray [dGy]:**Radiation absorbed dose expressed in decigrays, equal to one-tenth of a gray.**Centigray [cGy]:**Radiation absorbed dose expressed in centigrays, equal to one hundredth of a gray.**Milligray [mGy]:**Radiation absorbed dose expressed in milligrays, equal to one thousandth of a gray.**Microgray [µGy]:**Radiation absorbed dose expressed in micrograys, equal to one millionth of a gray.**Nanogray [nGy]:**Radiation absorbed dose expressed in nanograys, equal to one billionth of a gray.**Picogray [pGy]:**Radiation absorbed dose expressed in picograys, equal to one trillionth of a gray.**Femtogray [fGy]:**Radiation absorbed dose expressed in femtograys, equal to one quadrillionth of a gray.**Attogray [aGy]:**Radiation absorbed dose expressed in attograys, equal to one quintillionth of a gray.

**Formula:**The absorbed dose $D$ can be calculated using the formula:$D = \frac{E}{m}$where $E$ is the energy deposited by radiation and $m$ is the mass of the material absorbing the radiation.

**How to Convert:**To convert between different units of radiation absorbed dose, follow these steps:

**Identify the Initial and Target Units:**Determine the unit you have and the unit you want to convert to.**Find Conversion Factors:**Use conversion factors based on the relationships between the units.**Apply the Conversion Factor:**Multiply or divide the value you want to convert by the appropriate conversion factor.**Perform the Calculation:**Apply the conversion factor to the value you want to convert to get the equivalent value in the desired unit.

**Examples:**

**Conversion from Milligray [mGy] to Gray [Gy]:**$1\, \text{mGy} = 0.001\, \text{Gy}$To convert 500 milligrays to grays:$500\, \text{mGy} \times 0.001 = 0.5\, \text{Gy}$**Conversion from Rad [rd] to Microgray [µGy]:**$1\, \text{rd} = 10\, \text{µGy}$To convert 50 rads to micrograys:$50\, \text{rd} \times 10 = 500\, \text{µGy}$

By following these steps and using appropriate conversion factors, radiation absorbed dose values can be accurately converted between different units.
