An Online Scientific Calculator is a multifunctional tool designed for various numerical computations. Unlike a basic calculator limited to addition, subtraction, multiplication, and division, a scientific calculator supports more advanced operations, such as trigonometry, logarithms, and exponents. With our web-based engineering calculator, you can solve complex equations anytime and anywhere—no physical device is required.
Whether you’re a student, engineer, scientist, or anyone working with higher-level math, our calculator is trustworthy. It covers everything from basic algebra to advanced calculus and physics. One major advantage of an online calculator is its constant availability, delivering accurate results whenever you need them.
Our scientific calculator offers numerous functions to help solve almost any math problem. Notable features include:
Yes! All features are accessible at no cost. There are no hidden fees or premium upgrades required.
Absolutely. This calculator is fully web-based and responsive, so it runs smoothly on any modern device with internet access.
It offers trigonometry (sin, cos, tan, plus inverses), exponentials, logs (ln, log), roots, factorials, memory functions, and more—everything you need for algebra through advanced physics or engineering tasks.
You do need an internet connection initially to load the calculator. Once loaded, it relies on your browser for calculations. Having a stable connection ensures the tool remains functional and accurate.
In this particular calculator, ± applies absolute value. For negative numbers, type a minus (-
) before the digit.
Press M+ after entering a number to add it to memory, or M- to subtract. Then press MR to recall the stored value. This is helpful for multi-step operations without retyping each result.
This is normal. Like most calculators, it uses floating-point arithmetic.
Values like 0.9999999999
or 1.0000000002
can happen due to how computers represent decimals internally.
No. All calculations happen in your own browser. We do not store or track your input or results on the server.
