Introduction
In the world of frequency measurements, converting between different units is essential for scientists, engineers, and students. One such conversion is from exahertz (EHz) to picohertz (pHz). This article will guide you through the conversion process, explain the units involved, and provide practical examples.
The Units
What is Exahertz (EHz)?
Exahertz (EHz) is a unit of frequency in the International System of Units (SI).
- 1 EHz = 10¹⁸ Hz (hertz)
- It represents one quintillion (1,000,000,000,000,000,000) cycles per second.
- Used in high-frequency applications like astrophysics and advanced computing.
What is Picohertz (pHz)?
Picohertz (pHz) is an extremely small unit of frequency.
- 1 pHz = 10⁻¹² Hz
- It represents one trillionth of a hertz.
- Used in ultra-low-frequency measurements, such as geological processes.
Conversion Formula
To convert exahertz (EHz) to picohertz (pHz), use the following formula:Frequency in pHz=Frequency in EHz×1030Frequency in pHz=Frequency in EHz×1030
Explanation:
- 1 EHz = 10¹⁸ Hz
- 1 Hz = 10¹² pHz
- Therefore, 1 EHz = 10¹⁸ × 10¹² = 10³⁰ pHz
Example Conversion: 9.99 EHz to pHz
Let’s convert 9.99 EHz to pHz using the formula:9.99 EHz=9.99×1030 pHz9.99EHz=9.99×1030pHz
Step-by-Step Calculation:
- Take the value in EHz: 9.99 EHz
- Multiply by the conversion factor (10³⁰):9.99×1030 pHz9.99×1030pHz
- The result is 9.99 × 10³⁰ pHz
Conversion Table: EHz to pHz
| Exahertz (EHz) | Picohertz (pHz) |
|---|---|
| 1 EHz | 1 × 10³⁰ pHz |
| 5 EHz | 5 × 10³⁰ pHz |
| 10 EHz | 1 × 10³¹ pHz |
| 9.99 EHz | 9.99 × 10³⁰ pHz |
Practical Applications
1. Astrophysics & Cosmology
