Kilohertz to Megahertz Converter

Enter the frequency in kilohertz:

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

Example:

• 2500 kHz → MHz:

  $$\frac{\mathrm{<span\; style="font-size:\; small;">2500</span>}}{\mathrm{<span\; style="font-size:\; small;">1000</span>}}<span\; style="font-size:\; small;">=</span>\mathrm{<span\; style="font-size:\; small;">2.5</span>}\text{<span style="font-size: small;"> MHz</span>}$$

2. MHz to kHz

$$\boxed{{\displaystyle {\mathrm{<span\; style="font-size:\; small;">f</span>}}_{\text{<span style="font-size: small;">kHz</span>}}}}<span\; style="font-size:\; small;">=</span>{\mathrm{<span\; style="font-size:\; small;">f</span>}}_{\text{<span style="font-size: small;">MHz</span>}}<span\; style="font-size:\; small;">\times </span>\mathrm{<span\; style="font-size:\; small;">1000</span>}$$

Example:

• 3.6 MHz → kHz:

  $$\mathrm{<span\; style="font-size:\; small;">3.6</span>}<span\; style="font-size:\; small;">\times </span>\mathrm{<span\; style="font-size:\; small;">1000</span>}<span\; style="font-size:\; small;">=</span>\mathrm{<span\; style="font-size:\; small;">3600</span>}\text{<span style="font-size: small;"> kHz</span>}$$

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

1. Radio Tuning

   • 98.5 FM = 98.5 MHz = 98,500 kHz

2. Computer Processors

   • 3.2 GHz CPU = 3200 MHz = 3,200,000 kHz

3. 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.
