About Scientific Calculator

Scientific Calculator is a browser-based mathematics tool built around a simple idea: common calculations should be fast to access, easy to read, and accurate enough for serious everyday use.

Privacy by design

The calculator performs its core calculations in the browser. Expressions do not need to be uploaded to a calculation API just to obtain a result.

Accuracy and transparency

The product uses a dedicated mathematical expression engine and includes automated tests for scientific notation, operator precedence, fractions, and angle modes. As with any numerical software, results should be checked when a calculation has high-stakes consequences.
