Frequency Conversion Formulas
Complete formulas for converting between different frequency units including Hz, kHz, MHz, GHz, and specialized frequency measurements.
đ Basic Frequency Conversions
SI Prefix Conversions
Hz to kHz
Example: 15,000 Hz
15,000 Hz = 15 kHz
MHz to GHz
Example: 2,400 MHz
2,400 MHz = 2.4 GHz
Hz to MHz
Example: 100,000,000 Hz
100 MHz (FM radio)
Frequency-Wavelength Relationship
Frequency to Wavelength
c = 3Ã10⸠m/s, f = 100 MHz
100 MHz = 3 meter wavelength
Period to Frequency
T = 1 ms period
1 ms period = 1 kHz
