Math & Statistics Calculators
Step-by-step math and statistics tools: matrices, transforms, series, probability distributions, hypothesis tests, geometry, and percentages.
Top calculators
A short starting set for the most common math & statistics calculators workflows.
Spherical Coordinate Converter (Cartesian ⇄ Spherical)
Convert 3D points between Cartesian (x, y, z) and spherical (r, θ, φ) coordinates, with radian-based formulas, angle conventions, and a worked example.
Gambler's Ruin Probability Calculator | Bankroll Survival Odds
Estimate the chance that a bankroll starting at i reaches a target N before ruin under the classic gambler's ruin model.
Simpson Diversity Index Calculator (D, 1−D & 1/D)
Enter comma‑separated species counts to calculate Simpson’s D, 1−D (Gini‑Simpson), and 1/D. Includes interpretation, examples, and limits.
AHP Calculator: Pairwise Priority Weights and Consistency Ratio
Enter a 3x3, 4x4 or 5x5 pairwise matrix on Saaty's 1-9 scale. This AHP calculator returns principal-eigenvector priority weights plus lambda-max, CI, RI and CR.
Map Scale Distance Converter: Map Measurement to Ground Distance
Convert a measured distance on a map to the actual ground distance using a map scale ratio. Ideal for geography students and hikers.
K-Means Clustering Calculator – Centroids, WCSS and Plot
Run deterministic Lloyd k-means on x,y pairs: pick k, then read cluster assignments, centroid coordinates, within-cluster sum of squares and a scatter plot.
Laplace Transform Calculator for exp, sin, cos, and Powers of t
Calculate supported Laplace transforms of exponential, sine, cosine, and power-of-t functions as s-domain expressions.
