Calculator

Calculator is a practical calculator for everyday math and scientific calculations. It supports addition, subtraction, multiplication, division, percentages, parentheses, and full expressions, with the multiplication symbol displayed clearly as “×”. Scientific tools include sine, cosine, tangent in degrees, natural and common logarithms, exponents, squares, cubes, square roots, cube roots, nth roots, powers, factorials, absolute values, and the π and e constants. Reuse a result as your next input to work faster, and manage calculation history by viewing, reusing, deleting individual entries, or clearing everything at once. The built-in unit converter covers length, weight, temperature, area, volume, time, speed, pressure, energy, and data storage, with unit swapping, conversion details, and one-tap result copying. Calculations and history are handled locally on your device in a clean, easy-to-use interface.
