The least count is the value of the smallest scale division of the measurement instrument. Example: a ruler with marks 1 millimeter apart has a least count of 1 millimeter The least count of an instrument is the size of the smallest scale division on the instrument. The smaller the least count the more precise the instrument is said to be. For example a metric ruler which has millimeter marks has a least count of 1 mm or 0.1 cm. and when properly used it can make more precise measurements than one with centimeter marks.
The top and side rulers in Adobe InDesign CS6 help you arrange and align objects within the document. The default unit of measurement for these rulers is the pica, which equals 12 points. This measurement might not mean much to you, especially if you're designing a print publication on pages typically expressed in inches. In such cases, setting the rulers to inches might make more sense. InDesign makes it possible for you to change the horizontal and vertical rulers separately, so you can use different units for each ruler. Step 1.
