Unit conversion in Windows 7

In Windows 7 you don't have to rely on search engines or downloadable software to perform conversions between units of power, time, volume, and mass. Just use the built-in calculator.
1. Open the Calculator - click the Start button, select "All Programs", "Accessories", and then "Calculator".
2. When the Calculator appears select the "View" menu then "Unit Conversion". Or, press Ctrl + U.

3. A unit conversion pane appears to the right of the calculator. Underneath "Select the type of unit you want to convert", click the pull-down and select your unit type.
4. Underneath "From" type in the value of the beginning unit.
Convert between units of area, energy, temperature, volume, and more in Windows 7.

5. Underneath the value of the beginning unit, click the pull-down to choose the unit type.
6. Below "To", click the pull-down to choose the ending unit type.
When all values have been selected, the text box below "To" shows the value of the calculation. You can select the value with your mouse, then select "Edit" - "Copy" (or press Ctrl + C) to copy the resulting value. It can then be pasted into the main calculator window, Notepad, a word processing document, etc.
