All calculators
- Volume CalculatorCalculate the volume of a cylinder, box, sphere, cone, pyramid, or capsule in any unit, with the formula and every common unit conversion shown.
- Area CalculatorCalculate the area of a rectangle, circle, triangle, trapezoid, ellipse, parallelogram, or regular polygon in any unit — including acres and hectares.
- Surface Area CalculatorCalculate the surface area of a box, cylinder, sphere, cone, or capsule, split into lateral and end areas, with every common unit conversion.
- Triangle CalculatorSolve a triangle from three sides or two sides and the included angle — get every angle, the area, perimeter, heights, and the triangle's classification.
- Pythagorean Theorem CalculatorSolve a right triangle with a² + b² = c²: find the hypotenuse from two legs, or a missing leg from the hypotenuse, with the angles, area, and perimeter.
- Distance Between Two Points CalculatorCalculate the straight-line distance between two points from their coordinates, with the midpoint, slope, and the horizontal and vertical distances.
- Circle CalculatorEnter a circle's radius, diameter, circumference, or area and get all the others, plus π and the exact relationships between them.
- Circle Sector CalculatorCalculate the area, arc length, chord, and perimeter of a circular sector from its radius and central angle, in degrees.
- Regular Polygon CalculatorCalculate the area, perimeter, interior and exterior angles, apothem, and circumradius of a regular polygon from its number of sides and side length.
- Cone CalculatorCalculate the volume, slant height, lateral surface area, and total surface area of a right circular cone from its base radius and height.
- Trapezoid CalculatorCalculate the area, midsegment, and perimeter of a trapezoid from its two parallel sides, height, and the two legs.
