A system and method for converting coordinates on a computer graphics system so that objects drawn on a computer display screen will have the dimensions and location intended by the user when the object is printed. The user draws lines on the display screen, with the lines being aligned with marks on rulers which are also displayed along each axis of the display screen. The ruler marks are labeled in units, such as millimeters, which are often impossible to accurately display on the computer screen. The system then converts the coordinates to a high resolution coordinate system value that corresponds to the position and size of the object in relation to the labeled marks on the ruler. When the display screen is printed, the object is printed in accordance with the labels on the rulers rather than the displayed image of the object on the computer screen. Similarly, the high resolution value for the intended length of the object is used to display the image on the screen relative to the ruler when the object is moved about on the screen. The method may be easily implemented on a computer using graphics or desktop publishing software.
