Common Frequency Conversion Examples
| Conversion | Formula | Example |
|---|---|---|
| Hertz to Kilohertz | Hz ÷ 1000 = kHz | 5000 Hz = 5 kHz |
| Megahertz to Gigahertz | MHz ÷ 1000 = GHz | 2400 MHz = 2.4 GHz |
| RPM to Hertz | RPM ÷ 60 = Hz | 3600 RPM = 60 Hz |
| Gigahertz to Megahertz | GHz × 1000 = MHz | 3.5 GHz = 3500 MHz |
| Hertz to RPM | Hz × 60 = RPM | 50 Hz = 3000 RPM |

Frequency Ranges in Practice
Common Frequency Ranges
Audio Frequencies
20 Hz - 20 kHz (Human hearing range)
Radio Frequencies
• AM Radio: 530-1700 kHz
• FM Radio: 88-108 MHz
• WiFi: 2.4 GHz & 5 GHz
Computer Processors
• CPU: 1-5 GHz
• RAM: 1600-4800 MHz
• USB: 480 MHz (USB 2.0)
💡 Conversion Tips
- Quick kHz to MHz: Divide by 1000 (1 kHz = 0.001 MHz)
- Quick MHz to GHz: Divide by 1000 (1000 MHz = 1 GHz)
- Quick RPM to Hz: Divide by 60 (3600 RPM = 60 Hz)
- Quick Hz to RPM: Multiply by 60 (50 Hz = 3000 RPM)
