How to Use Google Calculator to Find Scientific Constants
Since Google was designed by engineers, you can expect to find some geeky tricks up its sleeve. One of these neat tricks is that Google has memorized dozens of physical constants and is ready and willing to show off its memorization skills at your request.
For example, if you type in speed of sound in any Google search box, Google will tell you what the speed of sound is, as shown below:
Not only does it tell you the speed of sound, but it goes one step further and clarifies that this is the speed of sound at sea level, since the speed of sound slows down as the air gets less dense at higher altitudes.
Let’s say you’re just not the meters per second kind of person. You think in MPH (miles per hour). Well, just tell Google and it will take care of the conversion. If you type in speed of sound in mph, Google tells you what the speed of sound is in units that make more sense to you.
If you’re like me, you might think that this is fun in a twisted sort of way. I wanted to stretch the limits of Google’s built-in calculator and decided to type in speed of sound in nanometers per millennium. I knew it would be an insanely high number, but Google is able to figure it out in only 0.09 seconds, as you can see below!
Not only can Google tell you the speed of sound, but it can also remind you of many constants. There are a lot that Google has memorized. You sort of have to experiment. However, more likely than not, Google will tell you the constant that you need to know whether you need it to finish your chemistry homework or just want to satisfy your curiosity.
Google can tell you how many atoms are in a mole (Avogadro’s number).
It also knows the elementary charge of an electron…
And finally the gravitational constant:
So next time you need to know a certain physical constant, just type it into Google’s search box. Google won’t leave you hanging.
