some of you asked me about the translation from centimeters to inch. Here you can do it!
put your cm (centimeters) in the second box and push the button "umrechnen" (translate) than will you get the INCH ! If you need further measurements, so you must push the butten "löschen" (delete) . After that you can translate again from cm to inch and again you put the data of centimeters in the second box
Hope it helps
