Hertz to Megahertz Converter

Enter the frequency in hertz:

A Hertz to Megahertz Converter is a tool used to convert frequency values from Hertz (Hz) to Megahertz (MHz). This conversion is essential in fields like telecommunications, computer engineering, radio broadcasting, and medical imaging, where high-frequency signals are common.

Understanding the Units

1. Hertz (Hz)

A. Definition: The SI unit of frequency, representing one cycle per second.

B. Usage: Measures low-frequency signals like audio waves, power line frequencies, and human hearing range.

C. Examples:

• Human hearing range: 20 Hz – 20,000 Hz (20 kHz)
• AC electricity (USA): 60 Hz

2. Megahertz (MHz)

A. Definition: 1 MHz = 1,000,000 Hz (10⁶ Hz).

B. Usage: Measures higher frequencies like radio waves, CPU clock speeds, and wireless signals.

C. Examples:

• M radio: 88 MHz – 108 MHz
• Wi-Fi signals: 2.4 GHz (2,400 MHz) or 5 GHz (5,000 MHz)
• Older CPU speeds: 500 MHz – 3,000 MHz (3 GHz)

Conversion Formula

The conversion between Hertz (Hz) and Megahertz (MHz) is simple:

$$\text{MHz}=\frac{\text{Hz}}{1,000,000}$$

Example Conversion:

• 5,000,000 Hz → 5,000,000 ÷ 1,000,000 = 5 MHz
• 250,000 Hz → 250,000 ÷ 1,000,000 = 0.25 MHz

Reverse Conversion (MHz to Hz)

$$\text{Hz}=\text{MHz}\times 1,000,000$$

Example:

• 2.4 MHz → 2.4 × 1,000,000 = 2,400,000 Hz

How to Use a Hertz to Megahertz Converter

1. Online Tools: Websites like RapidTables, UnitConverters, or CalculatorSoup provide instant conversions.

2. Manual Calculation: Use the formula MHz = Hz ÷ 1,000,000.

3. Spreadsheet (Excel/Google Sheets):

• Formula: =A1/1000000 (where A1 contains the Hz value).
