Calculate guitar and bass string tension from gauge, scale length, and pitch. Free string tension calculator for setup, string selection, and intonation tuning.
This tool applies a standard formula from the relevant domain. The computation is deterministic — given the same inputs, the result is always identical. The formula accounts for the primary variables that determine the output.
Ratio = f₂/f₁ | Cents = 1200 × log₂(ratio)The calculation requires: Lower Frequency (f₁), Higher Frequency (f₂). Each parameter contributes to the final result according to the formula above. Accuracy depends on the precision of your input measurements.

Check the expected unit for each input field (shown as suffix). Converting between imperial and metric units before entering values prevents calculation errors.
Ensure denominator values (divisors) are non-zero. The calculator validates this, but understanding which fields cannot be zero helps interpret results correctly.
Calculate just intonation interval ratios and cents deviation from equal temperament. Free interval ratio calculator for music theory and harmonic analysis. It applies the calculation formula (Ratio = f₂/f₁ | Cents = 1200 × log₂(ratio)). For example: a4 to e5 — perfect fifth — A typical use case demonstrating the calculator with representative values.
