Converting radiation dose rate units from hectogray per second (hGy/s) to picogray per second (pGy/s) is essential in fields like medical physics, radiology, and radiation protection. This guide provides a step-by-step conversion process, ensuring accuracy and efficiency.
Understanding the Units
Before converting, it’s crucial to understand the units involved:
- Hectogray per second (hGy/s): A unit measuring absorbed radiation dose rate, where 1 hGy = 100 grays (Gy).
- Picogray per second (pGy/s): A much smaller unit, where 1 pGy = 10⁻¹² grays (Gy).
The Conversion Formula
To convert hectogray per second (hGy/s) to picogray per second (pGy/s), use the following formula:pGy/s=hGy/s×1014pGy/s=hGy/s×1014
Why?
- 1 hGy = 100 Gy (since “hecto” means 10²).
- 1 Gy = 10¹² pGy (since “pico” means 10⁻¹²).
- Therefore, 1 hGy/s = 100 × 10¹² pGy/s = 10¹⁴ pGy/s.
Step-by-Step Conversion
Let’s convert 87.2 hGy/s to pGy/s:
- Multiply by the conversion factor:87.2 hGy/s×1014=87.2×1014 pGy/s87.2hGy/s×1014=87.2×1014pGy/s
- Express in scientific notation:8.72×1015 pGy/s8.72×1015pGy/s
Final Answer:
87.2 hGy/s = 8.72 × 10¹⁵ pGy/s
Conversion Table for Quick Reference
