How to use Scientific Calculator
Calculate expressions with brackets and common functions.
- Choose the operation and enter every labeled input, keeping units and the time period consistent.
- Calculate, compare the worked example below and inspect any warnings.
- Change one assumption to compare another scenario; keep the model’s limits in view.
Formula & calculation method
A restricted expression parser evaluates arithmetic, parentheses, powers and supported functions without executing arbitrary JavaScript. Trigonometric inputs use radians.
Input reference · 1 fields
These labels describe the calculation’s base units. Supported measurements can switch through the header’s region settings; follow the current workspace labels. Prefilled values are examples.
- Expression
- Enter a plain number with a decimal point if needed. The workspace shows an illustrative value, not a recommendation.
A quick example
sqrt(81) + 2^3 gives 17. sin(pi/2) gives 1.
Assumptions, edge cases & limits
- Use explicit multiplication such as 2 × 3 entered as 2*3.
- Invalid domains, division by zero and non-finite results are rejected.
- No arbitrary code is executed. Uses floating-point arithmetic; implicit multiplication is not supported.
Questions about Scientific Calculator
Does sin use degrees or radians?
Radians. To evaluate the sine of 30 degrees, enter sin(30*pi/180). Check the supported syntax before comparing with a calculator set to degree mode.
Can I paste JavaScript or spreadsheet formulas?
No. The input is a restricted maths expression, not a programming environment or a spreadsheet engine. Use arithmetic operators, parentheses and the functions supported by the parser.
Are my files or inputs uploaded?
Calculation and file processing run in your browser without a processing upload. Downloads go to your device. Choosing a next-step transfer creates a temporary local copy for that workflow. Region preferences are stored separately from tool inputs. See our privacy details.
Can I use this tool for free?
Yes. No signup, subscription or payment is required to use the tool or download its output. File tools have device and size limits; a smaller batch may work better on a phone.
