This is a code snippet that converts measurements such as degrees Celsius and Fahrenheit; centimeters and inches; meters and feet; kilometers and miles; kilograms and pounds; milliliters to ounces; and for fun, regular beers and tall beers. This was created for the expatriate American. It distinguishes singular and plural in the first value (for example, it will say 1 ounce, 2 ounces, and so on). Reloads if no values are given. It ignores extra spaces in the input, so -1 and - 1 (see the space) are the same. There's also a 'quick & dirty' check to make sure the first value given is not a letter, returns with a warning.
