Calculator

Want to add up a list of numbers, convert from miles to kilometers, or evaluate some other mathematical expression? Instead of using a piece of paper, your calculator, or a computer math software program, you can now solve mathematical problems with Google's built-in calculator function.

Simply enter the expression you'd like evaluated in Google's web search box and hit the ENTER key or click the "Google Search" button.

The Google Guide Calculator Reference provide a nice summary of some of Google's calculator features.

The calculator can evaluate mathematical expressions involving:

Basic Arithmetic

Compute expressions containing standard mathematical symbols. The following table lists operators that come between the two numbers on which they operate, e.g., to multiply 2 times 3, use 2 * 3.

Operator	Function	Example
+	Addition	[ 15.99 + 32.50 + 13.25 ]
-	Subtraction	[ 79 - 18 - 19 ]
*	Multiplication	[ 2 * 3 * 7 ]
/	Division	[ 378 / 9 ]
^ or **	Exponentiation (raise to a power of)	[ 4^10 ] or [ 4**10 ]
% of	Percent	[ 15% of 93.45 ]
mod or %	modulo (the remainder after division)	[ 15 mod 9 ] or [ 15 % 9 ]
the nth root of	calculates the nth root	[ 4th root of 16 ] [ cube root of 109 ] [ square root of 42 ] or [ sqrt(42) ]

Note: To do multiplication, you must include the * symbol; [ 3 * 4 ] will be calculated, 3 4 won't.

Advanced Math

Compute results involving mathematical constants, such as e, pi, i (the square root of -1), and mathematical functions. The following table lists just some of the functions built into Google's calculator.

Operator	Function	Example
sin, cos, tan, sec, csc, cot, etc.	Trigonometric functions (arguments are assumed to be in radians)	[ cos(pi/6) ] [ cosine(pi/6) ]
arcsin, arccos, arctan, arccsc, etc.	Inverse trigonometric functions	[ arccos(.5) ]
sinh, cosh, tanh, csch, arsinh, arccsch, etc.	Hyperbolic functions	[ cosh(6) ]
ln	Logarithm base e	[ ln(16) ]
log	Logarithm base 10	[ log(16) ]
lg	Logarithm base 2	[ lg(16) ]
exp	Exponential function	[ exp(16) ]
!	Factorial	[ 5! ]
choose	x choose y calculates the number of ways of choosing a set of y elements from a set of x distinct elements	[ 5 choose 3 ]

The following table lists just a few of the commonly used mathematical constants known to the calculator function.

Name and description	Example
base of the natural system of logarithms	[ e ]
pi, the ratio of the circumference to the diameter of a circle	[ pi/6 ]
imaginary number, i, which represents one of the two square roots of -1	[ i^2 ]
Euler's constant, gamma	[ e^gamma ]

Units of Measure and Conversions

Compute expressions involving different units. By default, units are converted to and results expressed in meter-kilogram-second (mks) units. Many units have both long and short names. Use whichever name you prefer.

Type of Units	Examples
Mass	kilogram or kg, grams or g, grains, pounds or lbs, carats, stones, tons, tonnes, etc.
Length	meters or m, miles, feet, Angstroms, cubits, furlongs, etc.
Volume	gallons, liters or l, bushels, teaspoons, pints, etc.
Area	square kilometers, acres, hectares, etc.
Time	days, seconds or s, centuries, sidereal years, fortnights, etc.
Electricity	volts, amps, ohms, henrys, etc.
Energy	Calories, British thermal units (BTU), joules, ergs, foot-pounds, etc.
Power	watt, kilowatts, horsepower or hp, etc.
Information	bits, bytes, kbytes, etc.
Quantity	dozen, baker's dozen, percent, gross, great gross, score, etc.
Numbering systems	decimal, hexadecimal or hex, octal, binary, roman numerals, etc. Prefix hexadecimal numbers with 0x, octal numbers with 0o and binary numbers with 0b. For example: 0x7f + 0b10010101.

Here are calculations that involve units.

[ 2 meters + 5 feet ]

Convert from one set of units to another by using the notation, x units in y units.

[ three quarters of a cup in teaspoons ]
[ 98.6 degrees Fahrenheit in degrees Celsius ]
[ 130 lbs in kg ]
[ 130 lbs in stones ]
[ 65 mph in kph ] or [ 65 mph in km/h ]

Warning: When your query includes "Calories" with a capital "C," Google returns kilocalories called "calories" by nutritionists.

[ 160 pounds * 4000 feet in Calories ]

Convert from one numbering system to another.

[ 1500 in hex ] or [ 1500 in hexadecimal ]
[ 64 in binary ]
[ LVII in decimal ]
