How To Use Google Calculator

Have you ever been doing something on the web and needed a calculator? Did you know you could use Google as a calculator? Here is a basic guide of how to use Google calculator. It’s easy and convenient to enter an equation into the Google search box and get an answer right in your Web browser. This why Google is Google, they have so many creative and useful ideas I have included a video so you can see it in action

Basic Calculations
To use Google as a calculator, all you have to do is enter your equation or formula into the search box and then click the Google Search button. The result of the calculation is displayed as shown, simple.

For Addition enter +, plus, or the word and
For Subtraction enter –, minus
For Multiplication enter *, times
For Division enter /, over
For Exponents enter to the (for example 2 to the 4th)

Here is an example, to add 2 plus 3. You would enter the following equation into the search box: 2 + 3. You can enter this with or without spaces. Click the Google Search button and you get your results.

If you want to divide 91 by 7, enter 91 / 7.
If you want to multiple 12 times 5 divided by 4, enter 12 * 5 / 4.

You can also created nesting equations by using appropriately placed parentheses. To divide the sum of 4 plus 3 by 5, you’d enter (4 + 3) / 5.

Google recognizes English-language queries as well as proper mathematical ones. For example, you can type 2 and 3 or 7 times 6 or even (4 plus 3) over 5.

Advanced Calculations and Constants
Google’s calculator isn’t limited to basic addition and multiplication. It can also handle more advanced calculations and functions. Google also knows a variety of mathematical and scientific constants, such as pi, Avogadro’s Number, and Planck’s Constant. It also knows the radius of the Earth, the mass of the sun, the speed of light, the gravitational constant, and a lot more.

To find the speed of light for example Enter speed of light,
Google returns 299,792,458 m/s.

For the radius of the earth Enter radius of earth,
Google returns 6378.1 kilometers.

To divide the radius of the earth by pi. Enter (radius of earth) / pi;
Google’s answer is 2030.21229 kilometers.

To multiply the radius of the Earth by the speed of light and then dividing the answer by Avogadro’s number enter (radius of earth) * (speed of light) / (avogadro’s number).
The answer is 3.17512652 × 10-09 m2⁄s.)

The next time you need to make a quick calculation you will now know how to use Google’s search bar as a calculator.
