Abstract

 

Classic Internet online unit converter is designed to input one single value to receive one converted value. Conversion of more then one unit, like feet and inches to centimeters, requires frequent switching between converters, annoying, time consuming process which may lead to errors.

This work describes new formats of online units’ converters and dedicated calculators, to significantly improve the conversion or calculation efficiency, receiving more useful and more handy information in less effort.

The improvements of new forms of online converters and calculators include:

*
p<>{color:#000;}. ComboBox

*
p<>{color:#000;}. Changing both units without “submit” button

*
p<>{color:#000;}. Few sets of data

*
p<>{color:#000;}. All relevant units together

*
p<>{color:#000;}. Feet plus inch in the same converter

*
p<>{color:#000;}. Default values in online complex calculators

*
p<>{color:#000;}. Comparing values between sets of data

*
p<>{color:#000;}. Auto-fill of input fields

*
p<>{color:#000;}. Automatic fill with specific pattern

*
p<>{color:#000;}. Correcting not reasonable inputs

*
p<>{color:#000;}. Automatic input of recommended value

*
p<>{color:#000;}. Automatic determination of input limits

*

[]Classic Form of Units Converter

 

Usually Internet online unit converter is designed to input one single value to receive one converted value. US units system is the main reason for the need of units’ converters. For example, Fahrenheit to Celsius, miles to kilometers, feet to meters, fraction of inch to millimeters, and this is only the beginning of very long list.

 

The classic online converter is dedicated to convert one specific unit to other specific unit. Such simple converter has one input field and one output space.

Usually such converter patiently waits until we shall complete to write and correct the input value, and when this is finished we have to click some button, which will tell the program to begin the calculations and to display the value of the converted unit. Such button may have any label like “submit”, “continue” or “calculate”.

Following is an example of such calculator:

 

Printout 0-1 – Classic unit converter

 

This online converter has the following elements:

#
p<>{color:#000;}. Input value label (inch)

#
p<>{color:#000;}. Output label (centimeter)

#
p<>{color:#000;}. One input field, to input the number of inches

#
p<>{color:#000;}. Output area where the result will be displayed at the end of the operation

#
p<>{color:#000;}. “Submit” button

 

To receive result for this very simple conversion, few steps are required:

 

Step 1: Open the inch-centimeter online converter

 

Step 2: Insert input value (number of inches)

 

Step 3: Click on “submit” button

 

Printout 0-4 – Displaying the result

 

One of the popular tasks related to conversion of inch-feet units to metric units is technical drawing. The US drawings dimensions are expressed in feet, inch and fraction of inch.

To convert feet to millimeters we need one converter, and to convert inches to millimeters we need another converter. As the drawing includes both feet and inch units, we shall have to switch frequently between the converters, annoying, time consuming process, which may result in errors related to the use of not correct converter.

[] Improvement 1 – ComboBox

 

ComboBox includes a list of units available at the converter.

In the above case of feet and inches, the ComboBox should include “feet” and “inch”.

 

Printout 1-1 – ComboBox unit converter

 

This online converter has the following elements:

#
p<>{color:#000;}. Input label (Insert Value)

#
p<>{color:#000;}. Output label (centimeters)

#
p<>{color:#000;}. One input field, to input the number of feet or inches

#
p<>{color:#000;}. Output area where the result will be displayed at the end of the operation

#
p<>{color:#000;}. ComboBox

ComboBox serves also as “Submit” button, once selection is done.

 

To receive the result, few steps of are required:

 

Step 1: Open the online converter

 

Step 2: Insert input value (number of feet or inches)
