using the marking measure. with a marking measure, you do not need to convert the measurements you have taken into units of measurement. instead, all there is to it, is to fit in the combined marking & measuring edges between the measurement points on the object being measured. the scale is automatically fixed at this length & with the help of the same measuring & marking edges, you can then etch the length on to the work-piece. you can do it once or several time & with unwavering precision. you do not even need to see properly in order to make exact measurements & markings.
