Scientific Calculator

Scientific Calculator is a simple and practical Android calculator that brings everyday calculations, advanced scientific operations, and unit conversions together in one app. It supports addition, subtraction, multiplication, division, percentages, positive and negative numbers, decimals, and nested parentheses, along with commonly used scientific functions such as sin, cos, tan, inverse trigonometric functions, natural and common logarithms, squares, cubes, arbitrary powers, square roots, cube roots, exponentials, factorials, and the constants π and e. You can switch between degree and radian modes at any time, while live results appear as you enter an expression. The built-in unit converter covers 10 categories: length, weight, temperature, area, volume, speed, time, data storage, pressure, and energy. It lets you quickly swap the source and target units and view all conversion results within the selected category. Calculation and conversion history is saved automatically, with options to restore or copy entries, delete individual records, or clear all history. Results can also be copied to the clipboard with a long press. The app adapts to both portrait and landscape layouts, offers light, dark, and system-default themes, and lets you disable key vibration and sound as needed, making it suitable for calculations at school, at work, and in everyday life.
