About Frequency Converter
Whether you’re tuning a guitar, designing a radio or setting an overclock, frequency units matter. Tooloria’s Frequency Converter supports hertz, kilohertz, megahertz and gigahertz, plus period (seconds) for waveform timing. A note-mapping feature shows musical pitch (A4 = 440 Hz). Everything runs offline—vital for lab benches with no external network.
