Multitasking has been one major part of improvements and updates that had been introduced into technological projects nowadays to make them better than their contending counterparts. We see the world evolving in to an age where everyone wants things miniarturised and can do almost all things.

The ultimate unit calculator has done a very wonderful job of combining tons of conversion units into a masterpiece for ease of access and use of the world. But there is one thing that can be added to make it even better:

Suggestion

Since the ultimate unit converter can be viewed from another perspective to be an advanced calculator with preset constants of interpolation and calculation, it will only be customary to suggest an addition of a scientific calculator interface. I suggest that the unitconverter add another interface to it application, and this is the scientific calculator. Users who are converting from one unit or the other are actually making some calculations ninety percent of the times (90%). So, to make their works easier and faster it will be good to have a scientific calculator on the app. Having a calculator on the application will also reduce the stress of having to copy numbers into another application before answers be gotten. This will prove the application more efficient.
I suggest that the scientific calculator have interfaces such as:

The simple addition interface

This is where simple operations can be done. Operations such as addition, subtraction, multiplication and division. Take for example the android calculator:

The advanced interface

This interface will allow users to calculate advanced operations such as sine, cosine, tangent of angles, e.t.c. The android calculator also has an advanced interface for a little advanced functions.

Some other functions can be added to this interface.

I suggest that there be a toggle on every page of the converter to switch to a calculator mode. This may be in place of the refresh button on each screen. And the refresh icon should be made into a swipe down gesture as we have it on google chrome android app and other apps.

Thank you.
