What is a Scientific Calculator?
A scientific calculator is an advanced calculator for solving more than basic addition, subtraction, multiplication, and division. It supports trigonometric functions, logarithms, powers, roots, constants, parentheses, and degree or radian angle modes.
TryFormatter's Scientific Calculator works directly in your browser and does not require signup. It is useful for students, teachers, developers, engineers, researchers, and anyone who needs a fast online calculator for math and science-related calculations.
What Can You Calculate?
This online scientific calculator helps solve common arithmetic, algebraic, trigonometric, and scientific expressions. You can use it for quick checks, homework support, engineering formulas, programming calculations, and everyday math tasks.
Basic Arithmetic
Calculate addition, subtraction, multiplication, division, decimals, and expressions with parentheses.
Trigonometry
Use sine, cosine, tangent, and inverse trigonometric functions with degree or radian mode.
Logarithms
Calculate common logarithms with log and natural logarithms with ln.
Powers and Roots
Solve square roots, squares, cubes, custom powers, reciprocals, factorials, and constants.
Basic Calculator vs Scientific Calculator
A basic calculator is good for everyday arithmetic. A scientific calculator is better when you need advanced functions such as trigonometry, logarithms, exponents, constants, and expression grouping.

| Percentages | Yes | Yes |
| Trigonometry | No | Yes, with DEG and RAD mode |
| Logarithms | No | Yes, supports log and ln |
| Powers and Roots | Limited | Yes, supports powers, roots, and factorials |
| Constants | No | Yes, includes π and e |
| Parentheses | Limited | Yes, supports grouped expressions |
Degrees vs Radians Explained
Angle mode matters when using trigonometric functions such as sin, cos, and tan. The same number can produce a different result depending on whether the calculator is set to degrees or radians.
- Degrees (DEG): A full circle equals 360 degrees. This mode is common in school geometry, basic trigonometry, surveying, and many everyday angle calculations.
- Radians (RAD): A full circle equals 2π radians. This mode is common in calculus, physics, engineering, programming, and higher mathematics.
Mode Selection Tip
Check the DEG/RAD mode before calculating trigonometric values. For example, sin(30) in degree mode gives 0.5, but sin(30) in radian mode gives a different result because the input is treated as 30 radians.

Common Mistakes to Avoid
Using the Wrong Angle Mode
Always check DEG or RAD before using trigonometric functions. A wrong angle mode is the most common reason for unexpected sine, cosine, or tangent results.
Entering Invalid Factorials
Factorial works only with non-negative whole numbers, such as 5!. Negative numbers and decimals are not valid factorial inputs in standard calculator use.
Forgetting Parentheses
Use parentheses when order matters. For example, (2 + 3) * 4 gives a different result from 2 + 3 * 4.
