SciLine: Scientific & Engineering Calculator

SciLine is a fully-featured scientific calculator that lets you write your equations as you would on paper. Fractions look like fractions, exponents look like exponents, and square roots look like square roots.

We’ve built in over 50 physical constants for easy access: from Boltzmann’s constant to the mass of a proton.

The symbolic output mode makes it easier to make sense of your answers: if your output is a rational fraction, a multiple of pi, or a square root, we’ll show you the result in those terms. In addition, we’ve added engineering output mode.

Behind the scenes, SciLine uses the gold standard for equation rendering—LaTeX—so your equations will always look great!
