- Math handicapped? Type the string you want to solve into google calculator and it will solve it. After you read the instructions, you can just type the phrase into the google search window and the answer will pop up. I particularly like this for 3.75 miles is how many kilometers? (Type: 3.75 miles/kilometer)
