How to Use Google Calculator to Convert Degrees to Radians and Radians to Degrees
With a few keystrokes, you can easily take advantage of the power of Google’s built-in Calculator to convert between degrees and radians. For example, let’s say that you want to convert 60 degrees into radians, all you have to do is type 60 degrees in radians into any Google search box. Here’s what you get:
Don’t worry about giving Google a big number to handle either. It can convert degrees that are over 360. It can even convert over 10,000° into radians:
It’s just as easy to go from radians to degrees. You can type in whole numbers, numbers with decimals, and even fractions. If you have 2.25 radians and want to convert that to degrees, you could simply type 2 1/4 radians in degrees into the search box. Here’s Google Calculator’s answer:
It’s easy as pie to incorporate π into your calculations. For example, if you want to know what 3π radians is in degrees, all you have to do is type in 3pi radians in degrees. No need to even use the π symbol, just type pi.
And we end up with an anaswer of 540 degrees, which makes sense, since 1π radians is 180 degrees, and 3 x 180 is 540.

How to Use Google Calculator to Convert Speeds
If you’ve ever taken a basic physics course, you know that the standard units that physics equations use for speed are meters per second. To many people in the world those units make perfect sense. However, for us metrically challenged Americans, it can be hard to think in metric units. Fortunately, you can let Google do the work for you.
Using Google to Convert Between Different Units of Speed
Let’s say that in a physics problem, we find that an object is moving at 14 m/s. If you have no idea how fast that is, but want to find out, all you have to do is use Google to convert it to miles per hour, which is done like this:
14 m/s in mph
That’s really all you have to do, and Google will show you how fast 14 meters per second is in miles per hour.
You can also go from the English system back to metric, as shown in the example below:
On another note, the 1992 edition of the Guinness Book of World Records reports the following:
In a speed test carried out in the Seychelles a male giant tortoise could only cover 15 feet in 43.5 sec (0.23 mph) despite the enticement of a female.
Now that’s not all impressive, but if that turtle wanted to impress his little turtle lady friend, he could boast, “Hey baby, I can walk over 378 million micrometers per hour at your enticement!” Now that sounds a lot better.
You may wonder how the turtle did all that math in his head… Well, he didn’t! He was using Google, of course!

How to Use Google Calculator to Find Factorials
The Google Calculator can easily handle factorials.
How Do You Do Factorials With Google Calculator?
All you have to do is type in the number, followed by an exclamation point.
An example would be 5! — which gives the following results in Google:
What Can I Do With Factorials?
Many people do not understand what exactly factorials can help them with. Basically, five factorial (5!) means 5 x 4 x 3 x 2 x 1, which gives us the answer of 120.
Factorials play a very important role in probability and statistics.
In probability, let’s say that you had five different colored balls that you were pulling out of a hat without looking. The colors are red, yellow, blue, green, and orange. Five factorial tells us that the probability of pulling out the red, then the yellow, then the blue, then the green, and finally the orange balls — all in that order — is 1 in 120, or less than 1%. There are exactly 120 combinations of orders that those balls can be pulled out of the hat in.
In statistics, let’s say that we have five children Bob, Laura, Steve, Jeff, and Liza. If we wanted to stand them all in a line, five factorial tells us that there are 120 different orders that we can have them stand in. Amazing!
Even more amazing is that if you add nine more kids to the mix, then there are over 87 billion combinations of orders that the kids can be lined up in, as shown below.
