Google displays the current service link in black and the others in blue.
After running a search on one service, you can click on another service's link to run a search on that service using the same terms. For example, when you click on the News link, your search will be repeated on Google's News service.

有兩份簡捷的 Google 蒐尋要訣:
The word "Beta" beside a service's name indicates that Google is testing and refining the service. Use the service, and if you are so inclined, provide feedback to Google on how the service can be improved.
Next, we'll look at many of the special search tools listed above, as well as:
This section ends with Google's feature history.
The search tips and behaviors described in Part I of Google Guide work with Google's special search tools, except in the following few cases. The synonym operator (~) currently works only on Web and Directory searches.

The results of these shortcuts appear to the right of a tag or specialized icon and above your search results.
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 builtin 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:
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.
Operator  Function  Example 
sin, cos, tan, sec, csc, cot, etc. 
Trigonometric functions (arguments are assumed to be in radians) 
[ cos(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 ] 
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, footpounds, 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.
Convert from one set of units to another by using the notation, x units in y units.
Warning: When your query includes "Calories" with a capital "C," Google returns kilocalories called "calories" by nutritionists.
Convert from one numbering system to another.
Long Name  Shorthand Notation 
Click the Link for the Approximate Value 
atomic mass units  amu or u  [ u ] or [ atomic mass units ] 
Astronomical Unit  au  [ au ] or [ astronomical unit ]

Faraday constant  
[ Faraday constant ] 
gravitational constant  G  [ G ] or [ gravitational constant ] 
magnetic flux quantum  
[ magnetic flux quantum ]

[ mass of a proton ] 
mass of each planet and of the sun  
[ m_mars ], [ m_earth ], [ m_uranus ], [ m_sun ] 
molar gas constant  
[ molar gas constant ] 
permeability of free space  
[ permeability of free space ] 
Planck's constant  h  [ h ] or [ Planck's constant ] 
radius of each planet and of the sun  
[ r_earth ], [ r_pluto ], [ r_sun ]

[ speed of sound ] 
Here are some calculations using builtin constants.
Note: If you go through the entire questionposting process and actually post a question, and if someone answers it, your credit card will be charged for the amount you specified. Finish this exercise only if you are willing to spend that amount.
