Windows 10 Tip: How To Use Cortana’s Hidden Calculator and Converter

If you have used Google long enough you probably already know that you can make Google also be your calculator or unit converter. Well, do you also know you can do the same with Cortana in Windows 10?

Let’s take look…

Assume Cortana is enabled on your Windows 10 computer, you can perform some simple math calculations by just pressing Windows key and typing the formula in the search box.Make sure your formula uses the correct standard operators, such as:

  • + for addition
  • – for subtraction
  • * for multiplication
  • / for division
  • % for percentages
  • ^ for exponentiation
  • () for grouping
  • etc.

The result of your calculation shows up at the top of the search result list.

If your formula or question is related to a unit conversion, Cortana will automatically use its built-in converter to do the job for you. That includes length, volume, temperature, time, energy, etc. Simply type the question in the search box, like “35 gallons in liters”, and Cortana will display the answer right at the top of the search result.

Note that the calculator or unit converter disappears as soon as you click away. You can’t copy the formula or its result from Cortana window either.
