Frequency Converter
Convert between hertz, kilohertz, megahertz, gigahertz, and terahertz with precision. Free online frequency converter tool.
This free tool allows you to convert between different units of frequency including hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), and terahertz (THz). Simply enter your value and select the units to convert from and to.
How This Tool Works
Our frequency converter uses precise conversion factors to convert between different units of frequency:
- 1 Kilohertz (kHz) = 1,000 Hertz (Hz)
- 1 Megahertz (MHz) = 1,000,000 Hertz (Hz)
- 1 Gigahertz (GHz) = 1,000,000,000 Hertz (Hz)
- 1 Terahertz (THz) = 1,000,000,000,000 Hertz (Hz)
The calculator ensures accuracy by first converting the input value to hertz (the base unit), then converting to the desired output unit.
Frequently Asked Questions
What is frequency and how is it measured?
Frequency is the number of occurrences of a repeating event per unit of time. It is measured in hertz (Hz), where 1 Hz means one cycle per second. Higher frequencies are measured in kilohertz (kHz), megahertz (MHz), gigahertz (GHz), and terahertz (THz).
Why do we use different frequency units?
Different frequency units are used for different applications. For example, radio waves are typically measured in MHz, computer processors in GHz, and visible light in THz. Using appropriate units makes the numbers more manageable and easier to understand.
How accurate is this frequency converter?
Our frequency converter provides results with 6 decimal places of precision, using standard conversion factors based on powers of 10. Since frequency units are decimal-based, conversions are exact and highly accurate.
Tips and Best Practices
For the most accurate frequency conversions:
- Use hertz for low frequencies (like audio)
- Use kilohertz for audio and radio frequencies
- Use megahertz for radio and wireless communications
- Use gigahertz for microwave and computer frequencies
- Use terahertz for extremely high frequencies
