Understanding Frequency Conversion
Frequency measures how many times a periodic event occurs within one second. It is fundamental in understanding sound waves, radio signals, and the clock speeds of digital electronics.
| Unit Type | Unit Name | Value in Hertz (Hz) |
|---|---|---|
| Standard | Hertz (Hz) | 1 Hz |
| Standard | Kilohertz (kHz) | 1,000 Hz |
| Standard | Megahertz (MHz) | 1,000,000 Hz |
| Standard | Gigahertz (GHz) | 1,000,000,000 Hz |
| Standard | Terahertz (THz) | 1,000,000,000,000 Hz |
| Rotational | Revolutions per Minute (RPM) | 0.01667 Hz |
| Physics | Radians per Second (rad/s) | 0.15915 Hz |
| Audio | Standard Tuning (Note A4) | 440 Hz |
| Utility | AC Power (US/Japan) | 60 Hz |
| Utility | AC Power (Europe/Asia) | 50 Hz |
Conversion Tip
The Hertz (Hz) is the derived SI unit of frequency. It is defined as one cycle per second. For high-speed technology like computer processors, we typically measure in Megahertz (MHz) or Gigahertz (GHz).
Quick Reference
- 1 kilohertz (kHz) = 1,000 Hz
- 1 megahertz (MHz) = 1,000,000 Hz
- 1 gigahertz (GHz) = 1,000,000,000 Hz
- 1 terahertz (THz) = 1,000,000,000,000 Hz
- 1 RPM (rev/min) = 0.016667 Hz
- 60 RPM = 1 Hz
- 1 rad/s ≈ 0.159155 Hz
- Human hearing range ≈ 20 Hz to 20,000 Hz
