Online Scientific Calculator for Student or Teacher

Online scientific calculator - Calculate the mathematics function online - The coolest calculator on the web.

Maybe this post is only suitable for those students or teachers, this information is about a website which provides a scientific calculator.

You should know what is scientific calculator? that's right, a calculator that not only calculate some basic functions as: +, -, *, /, but able to calculate the sine, cosine, tangent, logarithms, hexadecimal, binary, etc.

If you're having a task that requires a scientific calculator, you can try the service from With the online scientific calculator you can calculate many functions quickly.


This site was developed with the following philosophy:
  • Software should not be installed
Everything should be web based. We can think of a few exceptions like 3D games, but the calculator is not one of them. We do offer to install this calculator instead of the windows calculator. We do not see this as really installing software, but rather as replacing installed software with web based software, which is within our philosophy.
  • Cool and intuitive software
Software should be easy to use, without a need for a manual. User interfaces should be cool, the cooler the better.

What's wrong with conventional calculators?

Let’s take the windows calculator as an example.
  • What's the deal with drawing buttons for each digit on the screen when we have such buttons on the keyboard?
  • You can not type into a number. If you forgot a digit, you have to erase all last digits and retype them again. Try to type 12345, and then change to 19345.
  • You can perform just one operation at a time, no "complex" arithmetic like (2+3)*4
  • Why is there no history of previous calculations? The entire memory is 1 number (good old M+ and MR). PCs come today with megabytes of memory, why limit to one?
  • It's inconsistent. Try this: runs the windows calculator, Select View | Standard and type 1+2*3=. You should get 9 as the answer. Now change to View | Scientific, and type again 1+2*3=. This time you get 7.
  • No unit conversions. Does your current calculator know how many feet are 100 meters? How many Fahrenheit is 32 Celsius?
How can I replace my windows calculator?
And what's wrong with the Google calculator?
  • Do you really have to send a request across the globe to compute 12*5? Can't your computer do this?
  • No history of previous calculations
  • Read the privacy section on the top of this page. They do what we don't.


Now you can replace the old windows calculator with this cool online calculator. This is how it works:
  • Download and install a small program that will replace the windows calculator with this site.
  • If you run the windows calculator when connected to the internet, this web site will be opened. If you run the windows calculator when not connected, the old calculator will open.
We currently support windows 95, 98, 2000 and XP. If you would like us to support more operating systems, let us know!

Download Calcoolate.Exe - It's just 56k, should download in less than 3 seconds
. Once the download completes, run the file.

If you want to un-install and revert to the windows calculator, go to the control panel (Start | Settings | Control Panel, select Add or remove programs, find the entry and press the Remove button).
