Do you enjoy math? Are you very good at it? Okay, in other words, do you stink at math? Are you in a profession that requires you to be a genius at mathematics (however, you’re not even close to being one?) Or, do you just want to learn some different things about math?

If so, worry no more, because Google has come to your rescue yet again. No, Google hasn’t released another new software program, but they do offer a built-in calculator function right on Google’s Web site. Who knew?!

To use this, go to Google’s Web site and simply enter the expression you’d like to evaluate in the search box and hit Enter (or click the Google Search button). Google will do everything from basic functions of mathematics to calculating inverse trigonometric functions and it will do it all for you!

For example:

We can, of course, combine the different mathematics functions together. For example, (25+49) -10. Here, the function in the brackets is calculated first (the addition happens before the subtraction).

Similarly, if you want to do advance mathematics calculations or want to help your child study for that upcoming trigonometry test, you can do that with the Google calculator. Below is a list of common functions you can use with this feature.

If you believe in pushing the calculator’s limits by making it do illogical calculations, you can force it to evaluate an expression by using the equal sign ( = ). However, this will only work if the expression is mathematically resolvable (nope, 1/0 still won’t give a result).

For example: 25-256898-751-36587 =

Now, Google hasn’t limited itself to just basic or advanced mathematics functions. What’s maybe more useful to most users is the ability to convert between different units. For example, kilograms to pounds, meters to miles or from one numbering system to another, etc. The point to note is that the “in” operator is used to specify what unit you want the answer in. For example, 20 kilos in pounds or 256 miles in kilometers. “In” is your easy way out.

Another point that you should consider is that when it comes to conversion, many units have both long and short names, but no matter what you use, the answer will be the same.

 Units Examples Currency Australian Dollars (AUD), British pounds (GBP), Euros, US Dollars (USD) Mass kilogram or kg, grams or g, grains, pounds or lbs, carats, stones, tons, tonnes Length meters or m, miles, feet, Angstroms, cubits, furlongs Volume gallons, liters or l, bushels, teaspoons, pints Area square kilometers, acres, hectares Time days, seconds or s, centuries, sidereal years, fortnights Electricity volts, amps, ohms, henrys Energy Calories, British thermal units (BTU), joules, ergs, foot-pounds Power watt, kilowatts, horsepower or hp Information bits, bytes, Kbytes, etc. Quantity dozen, baker’s dozen, percent, gross, great gross, score, googol 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.

Here are some examples written out to help you better understand some of the things this calculator can calculate for you.

20 kilometers + 3 meters
1.36 Gigabytes in Megabytes
50 in Binary
170 centimeters in inches
660 in dozen
29 years in seconds
1,000 GBP in euros
Quarter of a cup in teaspoons

It even calculates cool things like how much space 10 hours of 128 Kbps sized MP3s take up.

The best way to maximize the benefit from this calculator is to experiment with it. The more familiar you are with the terms, the faster and more accurate your calculations will be. There is also a link that says “More about calculator” that you can click on to learn even more about the different things this calc can do.

So, now that you have gotten a little bit better with mathematics and Google (I hope anyway), can I challenge you to calculate how long is a kilometer in bytes? : )
