Google Calculator Cheat Sheet

Google Calculator is a hidden feature of Google search. You can type math expressions, unit conversions and many other questions that have a unique answer.the calculator can do more than addition. Subtraction (1-1), Multiplication (1*1), and division (1/1) are all simple, as are exponents (5^6). A complete list of the functions Google’s calculator can use can be found below, and includes advanced functions including square root (sqrt(110)) and percentage (5% of 300).
             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.

cosine(pi/3)
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)

TIPS (adapted from Google's Online Calculator Help)  
Parentheses can be used whenever they'll serve to make complicated expressions unambiguous, and also sets of parentheses can be used within parentheses; don't use brackets for grouping.
You can force the calculator to try to evaluate an expression by putting an equals sign (=) after it. This works only if the expression is arithmetically computable. For example, 1-800-555-1234= will return a result, but 1/0= will not (because dividing a non-zero number by zero is undefined and not computable).
Parentheses can be used to enclose the parts of your expression that you want evaluated first. For example, (1+2)*3 causes the addition to happen before the multiplication.
Google's calculator automatically balances unclosed parentheses.
A missing operator within an expression may default to an *, e.g., 6cos(2pi).
Feel free to experiment with the calculator as not all of its capabilities are listed here.
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   UNIT CONVERSION   EXAMPLES OF UNITS

  old units in new units  
Currency (money)   23 USD in Euros   US Dollars (USD), Euros, Britain Pounds (GBP)
Mass   130 lbs in kg   kilogram or kg, grams or g, grains, pounds or lbs, carats, stones, tons, tonnes
Length   3 miles in km   meters or m, miles, feet, Angstroms, cubits, furlongs
Volume   three quarters of a cup in teaspoons   gallons, liters or l, bushels, teaspoons, pints
Area   2 acres in sq km   square kilometers, acres, hectares
Temperature   98.6 Fahrenheit in Celsius or 98.6 f in c   Celsius or c, Fahrenheit or f
Time   1 year in seconds   days, seconds or s, centuries, sidereal years, fortnights
Electricity   100 volts in picovolts   volts or v, picovolts, amps or a, ohms, henrys
Energy   160 lbs * 4000 ft in Calories   Calories, British thermal units (BTU), joules, ergs, foot-pounds (Warning: When your query includes "Calories" with a capital "C," Google returns kilocalories called "calories" by nutritionists.)
Power   1 hp in watts, 500 V * 3 A in KW   watt or W, kilowatts or KW, megawatts or MW, horsepower or HP
Angle   90 degrees in radians
  degrees or radians
