How to use it
Fast scientific calculations without leaving the project page
Enter a formula directly or build it with the calculator buttons. Press = or the Enter key to calculate. The result can be reused with Ans, which is useful when a calculation has several steps.
Angle mode
Use DEG for common angle calculations in degrees. Switch to RAD when working with formulas or code that expect radians.
Number bases
Keep the expression in normal mathematical form and switch the result display between decimal, hexadecimal and binary for embedded or programming work.
Formula preview
The preview helps you check brackets, powers and functions before calculating, reducing typical typing mistakes in longer formulas.

FAQ
Scientific calculator questions
Does the calculator store my calculations?
The calculator keeps a local session history in your browser tab so you can reuse recent expressions. It is not submitted through a form by this plugin.
When should I use DEG or RAD?
Use DEG for angle values written in degrees, for example sin(30). Use RAD for formulas from mathematics, physics or programming libraries where angles are expected in radians.
Can I use it for electronics formulas?
Yes. It is suitable for quick supporting calculations such as ratios, ADC scaling, timing values, logarithms and binary or hexadecimal result checks.
