Supported Radiation Dose Rate Conversions

Our calculator supports full bi-directional conversion. You can convert the base unit (Gray/second) to any of the following prefixes and specific units, or vice versa:

  • Metric Prefixes (to/from Gray/second): Exagray/second, Petagray/second, Teragray/second, Gigagray/second, Megagray/second, Kilogray/second, Hectogray/second, Dekagray/second, Decigray/second, Centigray/second, Milligray/second, Microgray/second, Nanogray/second, Picogray/second, Femtogray/second, and Attogray/second.
  • Legacy & Equivalent Units: Rad/second (rad/s) and Rem/second (rem/s).
  • Physics & Energy Equivalents: Joule/kilogram/second (J/kg/s) and Watt/kilogram (W/kg).
  • Dose Equivalent Rates: Sievert/second (Sv/s).

Understanding the Units

The Gray (Gy)

The Gray is the SI derived unit of ionizing radiation dose, defined as the absorption of one joule of radiation energy per kilogram of matter (1 Gy = 1 J/kg). Therefore, a rate of one Gray per second is mathematically identical to one Joule/kilogram/second or one Watt/kilogram.

Rad and Rem

The rad (radiation absorbed dose) is a legacy CGS unit. One Gray is equal to 100 rads. Consequently, converting Rad/second to Gray/second requires dividing by 100. Similarly, the rem is a legacy unit for equivalent dose, where 100 rem equals 1 Sievert.

Sievert (Sv)

The Sievert is the SI unit for equivalent and effective dose. While Gray measures the absolute physical energy absorbed, Sievert measures the biological effect. For x-rays and gamma rays, the radiation weighting factor is 1, meaning 1 Gray/second equals 1 Sievert/second in these specific contexts.
