Measure the fine distance between two pitches in cents. A cent is one hundredth of an equal tempered semitone, so twelve hundred cents make an octave, and it is the standard unit tuners and microtuning tools use for small pitch differences. Enter two frequencies in hertz, or a plain ratio, and this tool returns the interval in cents using the formula twelve hundred times the base two logarithm of the ratio. Positive means the second pitch is higher, negative means lower. Cents let you describe how sharp or flat something is with real precision, compare tuning systems, or set microtonal offsets on a synth. For reference a just perfect fifth sits about two cents above the equal tempered fifth, and most people notice a difference of around five cents. Enter your numbers and read the result at once.
A cent is a fine unit of pitch where 100 cents equals one semitone, so 1200 cents make an octave.
It converts a frequency ratio or two pitches into a cents value so you can measure how far apart they are.
Cents describe the perceived pitch distance evenly across the range, while a Hz difference feels bigger at low pitches and smaller at high ones.
