ConverterFrequency Units Explained: Hz, kHz, MHz, and GHz
Use decimal SI scaling for Hz, kHz, MHz, and GHz while keeping frequency separate from angular frequency, bandwidth, data rate, and performance.

Use the Hz to kHz tool for the direct action. This guide stays focused on the explanation, tradeoffs, mistakes, and reference context behind that task.
Decimal SI Prefix Relationships
| Relationship | Exact factor |
|---|---|
| kHz to Hz | 1 kHz = 1000 Hz |
| MHz to kHz | 1 MHz = 1000 kHz |
| GHz to MHz | 1 GHz = 1000 MHz |
What Hertz Measures
Hertz expresses cycles per second. Binary powers of 1024 belong to explicitly binary data-storage prefixes and are not used for Hz, kHz, MHz, or GHz.
Angular frequency is measured in radians per second and differs by a factor of 2π. A data rate, channel bandwidth, or processor benchmark also needs information beyond the frequency label.
Display Precision
The prefix relationships are exact. Decimal input is calculated before finite display formatting, which removes unnecessary trailing zeroes. Apply any domain-specific significant-figure rule in the destination workflow.
