What is a Multi-Mode Calculator?
Multi-Mode Calculator is a powerful online calculation tool that integrates four calculation modes: Standard Calculator, Scientific Calculator, Base Converter, and Expression Mode. It supports complex mathematical operations, unit conversion, base conversion, and more. All calculations are performed on the browser side—secure and reliable.
Explanation of the Four Modes
| Pattern | Features |
|---|---|
| Standard Calculator | Basic arithmetic operations, percentages, square roots, squares, reciprocals, and switching between positive and negative numbers |
| Scientific Calculator | Trigonometric Functions, Inverse Trigonometric Functions, Logarithms, Exponentials, Factorials, π/e, Order of Operations, Switching Between Degrees and Radians |
| Base Converter | Convert between binary, octal, decimal, and hexadecimal, displaying detailed conversion steps |
| Expression Mode | Directly enter mathematical expressions, unit conversions (length/weight/speed/temperature), and complex number operations |
Supported Unit Conversions (Expression Mode)
- Length：km, m, cm, mm, inch, ft, yard, mile
- Weight：kg, g, lb, oz, ton
- Speed：km/h, mph, m/s
- Temperature：degCE, degF, degK
- Time：sec, min, hour, day, week, year
Keyboard Shortcuts
- Number keys 0–9: Enter a number
- Operators + - * /: Input operator
- Enter: Perform the calculation
- Esc: Clear/Reset
- Backspace: Delete the last character
Note:Expression mode supports math.js syntax for complex math and unit conversion. E.g. "100 mph to m/s" 可将 100 英里/小时转换为米/秒。
