## A COLLECTION OF ONLINE CALCULATORS |
|||||

<-------------------------------------------------------------------------------------------------------------------------------------------->
Let me start with a quick description of what's provided in this site. The term calculator does not necessarily refer to a small device with a keyboard and a display that performs arithmetic operations. In general, this term refers to any tool with specific built-in functions used to aid a computation. Here you will find virtual calculators as online substitutes for the pocket ones, as well as various unit conversion tools and other free virtual gadgets. Why would you need an online calculator if you have a "real" one? Well, firstly, most online computational tools here can be used just as you would use a real portable device. But in addition, you can copy and paste both the entry and the results into your document- something you can't easily do with a hand-held one. Below we also provide links to some selected useful off-site engineering tools. |
