Kilohertz to Megahertz Converter
Converting between kilohertz (kHz) and megahertz (MHz) is fundamental in radio communications, computer engineering, and signal processing. This guide provides clear conversion methods with practical examples.
Key Concepts
1. Kilohertz (kHz)
Definition: 1 kHz = 1,000 Hz
Applications:
Audio sampling rates (44.1 kHz)
AM radio frequencies (530-1710 kHz)
Older processor speeds
2. Megahertz (MHz)
Definition: 1 MHz = 1,000 kHz = 1,000,000 Hz
Applications:
FM radio (88-108 MHz)
Modern CPU clock speeds
Wi-Fi frequencies
Conversion Formulas
1. kHz to MHz
Example:
2500 kHz → MHz:
2. MHz to kHz
Example:
3.6 MHz → kHz:
Conversion Table
| kHz | MHz |
|---|---|
| 1 kHz | 0.001 MHz |
| 10 kHz | 0.01 MHz |
| 100 kHz | 0.1 MHz |
| 500 kHz | 0.5 MHz |
| 1000 kHz | 1 MHz |
| 2500 kHz | 2.5 MHz |
| 5000 kHz | 5 MHz |
Practical Applications
Radio Tuning
98.5 FM = 98.5 MHz = 98,500 kHz
Computer Processors
3.2 GHz CPU = 3200 MHz = 3,200,000 kHz
Audio Engineering
192 kHz sampling rate = 0.192 MHz
FAQ
Q: Why convert between kHz and MHz?
A: Different applications use different scales - radio engineers often work in MHz while audio technicians use kHz.
Q: How does this relate to GHz?
A: 1 GHz = 1000 MHz = 1,000,000 kHz
Q: What's the most common conversion needed?
A: Radio frequencies between 88-108 MHz (FM band) are often expressed in kHz for certain equipment settings.
