How to Use Google’s Hidden Calculator

Not only can you search Web with Google, you can also use it as a calculator. Google’s calculator is really more than an ordinary number cruncher. It can easily calculate both basic and advanced math problems, and it can easily convert measurements as it calculates. You do not even require to restrict yourself to numbers. Google can understand so many words and abbreviations and assess those expressions, too.

Google’s calculator was designed to explain and solve problems without a lot of math syntax, so you may infrequently find calculator results when you did not even understand you were searching for the answer to a math equation.

To use Google’s calculator, simply to go to Google’s search engine and type in whatever you would like to be calculated. for example, you could type:


and Google will return the result2+2=4. You can also type in words and get results. Type in

three plus three

and Google will return the result two plus two= Four

You know your results are from Google’s calculator when you see picture of the calculator to the left of the result.

Complex Math

Google can calculate more complex problems such as two to the twentieth power,


the square root of 287,


or the sine of 30 degrees.

sine(30 degrees)

You can even find the number of possible groups in a set. For instance,

24 choose 7

finds the number of possible choices of 7 items from a group of 24 items.

Convert and Measure

Google also can calculate and convert many common measurements, so you could get out how many ounces are in a cup.

oz in a cup

Google’s results reveal that1 US cup = 8 US fluid ounces. You can use this to convert just about any measurement to any other compatible measurement.

12 parsecs in feet

[blockquote shade= yes]37 degrees kelvin in Fahrenheit

You can calculate and convert in one step. Find out how many ounces you have when you have 28 times two cups.

28*2 cups in oz

Google says that 28 * 2 US cups = 448 US fluid ounces. Remember, because this is a computer based calculator, you must multiply with the * symbol, not an X.

Google recognizes most common measurements, including weight, distance, time, mass, energy, and monetary currency.

Math Syntax

Google’s calculator is designed to calculate problems without lots of complex math formatting, but sometimes it’s easier and more accurate to use some math syntax. For instance, if you want to evaluate an equation that looks like a phone number,


Google will probably confuse this with its hidden phonebook. You canforce Google to evaluate an expressionby using an equal sign.


This only works for problems that are mathematically possible to resolve. You can’t divide by zero with or without an equal sign.

You can force parts of an equation to be resolved before other parts by enclosing them in parenthesis.


Some other math syntax Google recognizes:

  • + for addition
  • – for subtraction
  • * for multiplication
  • / for division
  • ^ for exponential (x to the power of y)
  • % for modulo (to find the remainder after division)
  • choose X choose Y fines the number of possible subset groups of Y out of the set of X.
  • th root of creates the nth root of a number
  • % of finds percentages X % of Y finds X percent of Y.
  • sqrt finds the square root of the number that follows
  • ln logarithm base e
  • log logarithm base 10
  • lg logarithm base 2
  • ! factorial – This must follow the number you wish to factor.

If you be pleased about a more visual interface, you can use Soople’s Advanced Calculator, which uses Google’s engine to calculate.

Google’s calculator is not completely documented, so it may take some experimenting to discover all of the hidden features.
