Result: 4.5 MHz equals 4500 kHz
Converting 4.5 megahertz (MHz) to kilohertz (kHz) results in 4500 kHz. This is because 1 MHz equals 1000 kHz, so multiplying 4.5 by 1000 gives the value in kHz.
To explain further, MHz and kHz are units measuring frequency, where “mega” means million and “kilo” means thousand. Since 1 MHz = 1000 kHz, converting involves multiplying the MHz value by 1000, shifting the decimal point to get the correct kilohertz value.

Conversion Formula
The conversion from megahertz to kilohertz uses the formula: khz = mhz × 1000. This works because “mega” indicates a million units, but since we are converting to “kilo” units, which are thousand, the scale factor is 1000. For example, 4.5 MHz times 1000 equals 4500 kHz.
Mathematically, if you have a value of x MHz, you multiply x by 1000 to get the value in kHz. This method shifts the decimal three places to the right, converting the larger MHz measurement into the smaller kHz measurement without changing the actual frequency.
Conversion Example
- Convert 2 MHz to kHz:
- Multiply 2 by 1000
- 2 × 1000 = 2000
- Answer: 2000 kHz
- Convert 10 MHz to kHz:
- Multiply 10 by 1000
- 10 × 1000 = 10,000
- Answer: 10,000 kHz
- Convert 0.75 MHz to kHz:
- Multiply 0.75 by 1000
- 0.75 × 1000 = 750
- Answer: 750 kHz
- Convert 5.25 MHz to kHz:
- Multiply 5.25 by 1000
- 5.25 × 1000 = 5250
- Answer: 5250 kHz
- Convert 1.2 MHz to kHz:
- Multiply 1.2 by 1000
- 1.2 × 1000 = 1200
- Answer: 1200 kHz

Conversion Definitions
mhz
Megahertz (MHz) is a unit measuring frequency equal to one million cycles per second, used in radio, telecommunications, and digital electronics. It represents the speed or frequency of oscillations or signals, often in wireless communication contexts.
khz
Kilohertz (kHz) is a unit of frequency equal to one thousand cycles per second, commonly used in audio, radio, and signal processing. It indicates how many oscillations or cycles occur within one second, smaller than a megahertz.
Conversion FAQs
How can I quickly convert 4.5 MHz to kHz without a calculator?
Simply multiply 4.5 by 1000, because the conversion from MHz to kHz involves a scale factor of 1000. So, 4.5 × 1000 = 4500, making the process straightforward and fast.
Why does multiplying by 1000 convert MHz to kHz?
This is because “mega” indicates a million, but in the context of MHz to kHz, you’re shifting the decimal three places to the right, as 1 MHz equals 1000 kHz. Multiplying by 1000 directly scales the measurement down to kilohertz.
Are MHz and kHz used in different fields?
Yes, MHz is often used in radio frequency and telecommunications, while kHz is common in audio signals and low-frequency radio applications. Their usage depends on the scale and context of the signals being measured.
