What Is This Tool?
This unit converter transforms dose rate measurements from petagray per second (PGy/s), a very large radiation absorbed dose rate, into joule per kilogram per second (J·kg⁻¹·s⁻¹), an equivalent and widely recognized unit of energy absorption per mass per time.

Tips & Best Practices
-
Ensure the value entered represents extremely high dose rates appropriate for PGy/s
-
Use the conversion output for comparison and calculations in radiation-related fields
-
Be aware of instrumentation limits when working with petagray-level dose rates
-
Cross-check conversion results when applying to safety-critical scenarios
Limitations
-
Petagray/second applies only to very high dose rate situations not common in routine radiation assessments
-
Measurement precision can be limited by detector saturation at these extreme rates
-
Not suitable for typical medical or environmental radiation dose evaluations
Frequently Asked Questions
-
What does petagray per second measure?
-
Petagray per second quantifies an extremely high absorbed radiation dose rate—equal to 10^15 grays per second—indicating how rapidly radiation energy is deposited per unit mass.
-
Is joule per kilogram per second different from gray per second?
-
No, joule per kilogram per second (J·kg⁻¹·s⁻¹) is equivalent to gray per second (Gy/s) as both express absorbed dose rate in terms of energy per mass and time.
-
When should I use this conversion?
-
Use this conversion when working with very high radiation dose rates such as in nuclear safety, high-energy physics, radiotherapy planning, or astrophysical radiation modeling.
Key Terminology
-
Petagray/second (PGy/s)
-
An SI-derived unit representing 10^15 grays per second, quantifying extremely high absorbed radiation dose rates.
-
Joule/kilogram/second (J·kg⁻¹·s⁻¹)
-
A unit expressing the energy absorbed per kilogram of material per second; equivalent to gray per second for absorbed dose rates.
-
Absorbed Dose Rate
-
The rate at which ionizing radiation energy is deposited in a material or tissue, typically measured in grays per second.
