Radiation-Absorbed Dose Converter
Comprehensive Radiation-Absorbed Dose Converter
Radiation-absorbed dose quantifies the energy deposited by ionizing radiation in a unit mass of material. Expressed in rad (rd) or gray (Gy), it is a critical parameter in radiological protection and dosimetry. Our Radiation-Absorbed Dose Converter allows you to convert between various units—from the SI base unit (rad) to larger multiples (exagray, petagray, teragray, gigagray, megagray, kilogray) and smaller multiples (hectogray, dekagray, decigray, centigray, milligray, microgray, nanogray, picogray, femtogray, attogray). It also covers related units like rad/second, joule/kilogram/second, watt/kilogram, sievert/second, and rem/second.

How Does It Work?
The converter uses a two-step process:
Convert to the Base Unit:
The input value is first converted into rad (rd) using the conversion factor of the selected “From” unit.Convert to the Target Unit:
The value in rad is then converted into your chosen “To” unit using its corresponding conversion factor.
This approach ensures precise and consistent conversions for all your radiation dose calculations.
