Windows 7 comes with a calculator's ultra-utility function

I really don't know, the original Win7 calculator has been so cool! In addition to the most basic mathematical calculations, it has added super-practical functions such as date calculation, unit conversion, fuel consumption calculation, monthly installment calculation and so on. Let's take a few simple cases to introduce them one by one...

Date calculation

Sometimes we need to calculate the number of days between two date intervals, from now to a certain month It takes a few days and weeks to go. For example, suppose the company leader asked us to submit a work report on the 18th of next month. Now we want to know how long it will be from this deadline. With the help of a calculator, things become very simple, and you don't have to worry about your fingers any more. Simply click on 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, this example is There are 2 weeks and 6 days (20 days in total), as shown below:

Unit conversion

Unit conversion of Windows 7 calculator The function is also very practical. For example, we often hear 1 carat, 1 ounce, etc., but not everyone knows how much these "unfamiliar" weight units are equal. At this point we can open the calculator and click on the "View" menu, "Unit Conversion" menu item. Then select the type of unit you want to convert in the details pane on the right. For example, you can select “Weight/Quality”, then select the specific unit to be converted (for example, “Carat”), and the target unit (for example, “G”). , then specify how many carats, the results will be displayed immediately. This example shows that 1 carat is equal to 0.2 grams, as shown below:
