Perform Unit Conversions with the Windows 7 Calculator

Want to easily convert area, volume, temperature, and many other units?  With the Calculator in Windows 7, it’s easy to convert most any unit into another.

The New Calculator in Windows 7

Calculator received a visual overhaul in Windows 7, but at first glance it doesn’t seem to have any new functionality.  Here’s Windows 7’s Calculator on the left, with Vista’s calculator on the right.

But, looks can be deceiving.  Window’s 7’s calculator has lots of new exciting features.  Let’s try them out.  Simply type Calculator in the start menu search.


To uncover the new features, click the View menu.  Here you can select many different modes, including Unit Conversion mode which we will look at.


When you select the Unit Conversion mode, the Calculator will expand with a form on the left side.


This conversions pane has 3 drop-down menus.  From the top one, select the type of unit you want to convert.


In the next two menus, select which values you wish to convert to and from.  For instance, here we selected Temperature in the first menu, Degrees Fahrenheit in the second menu, and Degrees Celsius in the third menu.


Enter the value you wish to convert in the From box, and the conversion will automatically appear in the bottom box.


The Calculator contains dozens of conversion values, including more uncommon ones.  So if you’ve ever wanted to know how many US gallons are in a UK gallon, or how many knots a supersonic jet travels in an hour, this is a great tool for you!



Windows 7 is filled with little changes that give you an all-around better experience in Windows to help you work more efficiently and productively.  With the new features in the Calculator, you just might feel a little smarter, too!

    the calculator might be the only app from accessories that is useful. for all others i use replacements for viewing images, listening and viewing media, editing text or code snippets, managing files etc…

    I use calc98 as a replacement for the calculator. Not only does it do all of this fun stuff, but also RPN and working with different number bases (2 or 16)

    I think the most useful feature in the Win7 calculator is the “History” option. It allows me to access intermediate results without having to bother with those memory keys. Thank you Microsoft. It’s about time!

    The Date Calculation feature is also a good one.

    Google has a built in calculator that can convert automatically for you too.

    e.g. type what you would like converted like so…

    212 fahrenheit in celsius

    500 mph in kph

    1 MBps in kbps

    [As well as doing normal mathematical calculations !!]

    If you need a serious calculator for your daily work, you should try DeskCalc for Windows.
