Get quick answers when you enter math equations or conversions in the Google Search box.
Calculator
You can use the calculator for any math problem you want to solve, like calculating the tip at a restaurant, making graphs, or solving geometry problems.
- Type your equation into the search box on google.com or
- Search for:
Calculator
- Arithmetic
- Functions
- Value of physical constants
- Base and representative conversion
You can graph complicated equations quickly by entering your functions into the search box. You can see what a sample equation looks like here.
Tips
- To plot multiple functions together, separate the formulas with a comma.
- To explore the function in more detail, zoom in and out and pan across the plane.
Functions you can graph
- Trigonometric
- Exponential
- Logarithmic
- 3D graphs (for desktop browsers that support WebGL)
"This function may not be plotted correctly"
The plotting algorithm detected one of these:
- Too many asymptotes
- Too many transitions of the function from defined to undefined regions
- Too many points on the graph that might not represent the current function value due to high volatility
Try to pan or zoom the function to a different region.
"Cannot zoom further"
The pan or zoom action can’t be performed because of numerical limitations. Try to pan or zoom the function to a different region.
"Cannot pan in this direction"
The pan or zoom action can’t be performed because of numerical limitations. Try to pan or zoom the function to a different region.
You can find geometry formulas and answers to complex geometry problems using Google Search.
Open the geometry calculator
- Search Google for a formula, like:
Area of a circle. - In the box that says "Enter value," type the values you know.
- To calculate a different value, next to "Solve for, " click the Down arrow
.
.Shapes & formulas you can use
- Supported shapes: 2 and 3 dimensional curved shapes, platonic solids, polygons, prisms, pyramids, quadrilaterals, and triangles.
- Supported formulas and equations: Area, circumference, law of sines and cosines, hypotenuse, perimeter, Pythagorean theorem, surface area, and volume.
Examples
what is the volume of a cylinder with radius 4cm and height 8cmformula for a triangle perimeterfind the diameter of a sphere whose volume is 524 gallonsa^2+b^2=c^2 calc a=4 b=7 c=?
If the calculator doesn't show up when you enter in an equation:
- Make sure your equation is something that can be computed. For example, if you search for "
7*9/0," you won’t see the calculator pop up because dividing by zero doesn’t create a value. - If it still isn't showing up, try adding
=to the beginning or end of your search.
Unit converter
You can use the unit converter to convert from one measurement to another. For example, you could convert from Celsius to Fahrenheit or cups to liters.
- Type your conversion into the search box or
