Scientific Calculator

Engineering calculator reviewed for preliminary design use · Last updated: March 2026

Scientific calculator supporting trigonometric functions (sin/cos/tan), inverse trig, logarithms (log/ln), exponentials, powers, and square roots for engineering calculations. Includes DEG/RAD toggle and calculation history.

Web Scientific Calculator for Engineers

Perform complex technical calculations directly in your browser when a physical calculator isn't available.

Key Functions

  • Trigonometry: sin, cos, tan, and inverses (for pipe offsets, vector analysis).
  • Log/Exp: log, ln, e^x (for pH, decay rates, growth projections).
  • Powers/Roots: Essential for flow-pressure relationships.

Includes history and memory features to support efficient calculation workflows.

Frequently Asked Questions

What functions are supported?

Trigonometric (sin, cos, tan and inverses), logarithmic (log, ln), exponential (exp), power (^), square root (√), factorial (!), and constants (π, e). DEG/RAD toggle for angle units.

Can I use engineering notation?

Yes. Enter numbers in scientific notation like 1.5e6 for 1,500,000. The calculator supports parentheses for complex expressions and follows standard operator precedence (PEMDAS).
