Calculators

Calculates a pitcher's Fielding Independent Pitching (FIP), an estimate of a pitcher's effectiveness based on strikeouts, walks, hit batsmen, and home runs.

Performs a t-test (one-sample, two-sample, or paired) to compare means and determine statistical significance.

Calculates pace (time per distance unit) based on distance and time, or vice-versa, for activities like running or cycling.

Calculates the output voltage from a simple circuit that divides a source voltage across two resistors.

Converts between quarts (US liquid) and pounds, based on the density of the substance. This calculator uses the density of water (1.0 kg/L or approximately 2.086 lbs/quart) as a default. You can adjust the density to match the substance you are measuring.

Calculates the reaction quotient (Q) to determine the direction a reversible reaction will shift to reach equilibrium.

Calculates the spatial period of a wave (distance over which the shape repeats) based on speed and frequency (λ = v/f).

Calculates the standard error, which measures the accuracy with which a sample represents a population. It's commonly used for the standard error of the mean (SEM) and the standard error of the proportion.

Calculates the relationship between the output gap and cyclical unemployment based on Okun's Law.

Calculates the effectiveness of a treatment in reducing the number of microorganisms by measuring the log reduction value.
