Gray/second to Exagray/second Converter
Easily convert radiation dose rates between Gray per second (Gy/s) and Exagray per second (EGy/s). Enter a value in either field to compute the vice-versa conversion.
Contextual Information: What are PGy/s and Gy/s?
To accurately perform this conversion, it is important to know exactly what these units measure:
- Gray (Gy): The Gray is the standard SI derived unit of ionizing radiation dose. It measures the amount of radiation energy absorbed by one kilogram of matter (1 Gy = 1 Joule per kilogram).
- Gray per Second (Gy/s): This is the unit of absorbed dose rate. It indicates how much radiation dose is absorbed every single second.
- Petagray per Second (PGy/s): The prefix “Peta” represents a factor of 1015 (one quadrillion). Therefore, one Petagray per second is an incomprehensibly large radiation dose rate, typically only discussed in theoretical physics, cosmic phenomena, and high-energy particle research.
The Conversion Formula
Because the SI prefix “Peta” stands for 1015, converting from Petagrays per second to standard Grays per second requires multiplying your value by one quadrillion (1,000,000,000,000,000).
Formula:
Gy/s = PGy/s × 1015
or
Gy/s = PGy/s × 1,000,000,000,000,000
Example Calculation: If you have a theoretical dose rate of 3.5 PGy/s, you would multiply 3.5 by 1015 to get 3,500,000,000,000,000 Gy/s.
A Conversion Table (Quick Reference)
For quick calculations, use the reference table below to see common Petagray/second to Gray/second conversions at a glance. Due to the vast scale of these numbers, scientific notation is the most practical way to read them.
| Petagray/Second (PGy/s) | Gray/Second (Gy/s) | Scientific Notation (Gy/s) |
|---|---|---|
| 0.1 PGy/s | 100,000,000,000,000 Gy/s | 1 × 1014 |
| 1 PGy/s | 1,000,000,000,000,000 Gy/s | 1 × 1015 |
| 2 PGy/s | 2,000,000,000,000,000 Gy/s | 2 × 1015 |
| 5 PGy/s | 5,000,000,000,000,000 Gy/s | 5 × 1015 |
| 10 PGy/s | 10,000,000,000,000,000 Gy/s | 1 × 1016 |
| 50 PGy/s | 50,000,000,000,000,000 Gy/s | 5 × 1016 |
| 100 PGy/s | 100,000,000,000,000,000 Gy/s | 1 × 1017 |
Why Measure in Petagrays?
While standard medical radiation therapies, radiological protection, and industrial applications use fractions of a single Gray (such as milligrays or micrograys), a Petagray measures energy deposition on a vastly different scale. You will rarely encounter PGy outside of theoretical models detailing the energy output of astronomical events, plasma physics, or hypothetical high-energy calculations. Knowing how to step down from the “Peta” prefix to the base unit is highly useful for physics students and researchers analyzing monumental scales of energy transfer.
