Need a fast frequency conversion? You're in the right place. Converting between Hertz (Hz), Megahertz (MHz), and Gigahertz (GHz) is simple once you know the rule of 1,000.

The Golden Rule of Frequency Conversion

The relationship between frequency units is based on the number 1,000:

• 1 kHz = 1,000 Hz

• 1 MHz = 1,000 kHz

• 1 GHz = 1,000 MHz

This means to convert between them, you just need to multiply or divide by 1,000.

The Easy Trick: Move the Decimal Point

• To go to a LARGER unit (e.g., Hz to kHz): Divide by 1,000 (move the decimal 3 places to the left).

• To go to a SMALLER unit (e.g., MHz to kHz): Multiply by 1,000 (move the decimal 3 places to the right).

Step-by-Step Examples

• Convert 2,400 MHz to GHz (Common Wi-Fi Frequency):
  We're going from a smaller unit (MHz) to a larger one (GHz), so we divide by 1,000.
  2,400 / 1,000 = 2.4 GHz

• Convert 101.1 MHz to kHz (FM Radio Station):
  We're going from a larger unit (MHz) to a smaller one (kHz), so we multiply by 1,000.
  101.1 × 1,000 = 101,100 kHz
