Friends,
In every Window Operating System there is a Calculator available and everyone of us uses this Calculator very frequently. Most of us use this Calculator for calculation purpose only. Some uses its Scientific version also. But do you know, you can calculate your present Age (How old are You) by just entering your Date of Birth and Today's date. Its so easy to do so. You can do so by pressing Ctrl+E key after opening the Calculator. By pressing Ctrl+E, one additional window will open in the Calculator. There is a option "Calculate the difference between two dates" followed by From Date and To Date fields. You have to just fill your Date of Birth in the From Date field and in To Date field today's current date is already there. so in the Difference column you will see your AGE in Years, Months, Weeks and Days.
You can also convert Units very easily by just pressing Ctrl+U button. In the next window you can select the type of Unit you Want to convert i.e. Area, Energy, Length, Time, Power, Pressure etc. Suppose you want to convert Square Yards to Square Feet. Then first you have to select Area then in From field enter the Square Yards and it will convert it to Square Feet by selecting Square Feet in To field.
And there are lots of more functions which we just can't imagine by using the Functions of Calculators.
