Questions guitarists ask

Are the GuitarMath tools free?
Yes. Every tool is free, runs in your browser and needs no account. Your settings save on your own device.
Where do the numbers come from?
From standard physics and music theory (equal temperament with A4 = 440 Hz) and from manufacturers' published specs. Each tool shows its formula and links its sources.
