Introducing the rich and practical functions of Win7 calculator

Unknowingly, I have been using Win7 for more than three years. I was deeply attracted by the gorgeous Win7 theme and Win7 desktop from the beginning, and I was even more conquered by the many times the powerful functions of XP! Today I will introduce to you the magical Windows7 multi-function calculator. Although it is small and exquisite, it contains rich and practical functions that cannot be ignored.

date calculation

Sometimes we need to calculate the number of days between two dates, that is, how many months, weeks and days will pass from now to a certain day of a certain month. For example, suppose the company leader requires us to submit a work report on the 18th of next month, and now we want to know how long it is until this deadline. With the help of a calculator, things become very simple, and you no longer have to pinch your fingers to calculate slowly. Just click the "View" menu, "Date Calculation" menu item in the calculator window, then enter the target date in the detailed pane on the right, and click the "Calculate" button to get the result. In this example, there are 2 weeks and 6 days left (20 days in total), as shown in the figure below:

Unit conversion

The Windows 7 calculator's unit conversion feature is also very useful. For example, we often hear expressions such as 1 carat and 1 ounce, but not everyone knows exactly how much these "unfamiliar" weight units equal. At this time we can open the calculator and click the "View" menu, "Unit Conversion" menu item. Then select the unit type to be converted in the detailed pane on the right, for example, you can select "weight/mass", then select the specific unit to be converted (for example, "carat"), and the target unit (for example, "gram"), and then specify how many carats it is, and the result will be displayed immediately. This example shows that 1 carat is equal to 0.2 grams, as shown in the figure below:
