Temperature Converter

Features

• Cursor is in the Temperature field when the page loads.
• After each result, the value in the Temperature field is selected. This allows you to type the next value without having to move there and delete the previous entry.
• Results do not appear to be within a form field (in recent browsers).
• In the result, when the temperature on either side of the equation is 1 or -1, it is written as the singular “1 degree.”
• Result on right side of equation is rounded to a maximum of two decimal places.
• Three different informative error messages for these cases:
  • Entering nothing
  • Entering non-numeric characters
  • Ending an entry with C or F — for example “32 f” or “100C”
    (some users may initially do this because instructions are not provided)
