Click the drop down on the left to set the unit you want to convert from, click the one on the right to set the unit you want to convert to. Click the "Set Number to Convert" button to set the number you want to convert. Click the "CONVERT" button to convert your number to convert in your unit to convert in to the unit to convert to. If the button is dimmed, that means you didn't fill in all the information it needs. You can only click the button when it is not dimmed. The answer will appear on the top of the screen, and above the drop down on the right, though the one on the top will stay even when the one above the drop down is gone.
All by me.
