Map Scale
When trying to find scale on maps I've used the Natural Scale ruler, for years. OCLC users have an alternative, the CalcScale macro.
How it works: The macro presents a dialog box in which to enter the two numbers of the ' scale ratio (including decimals, if necessary) and their corresponding units of length. ' It then calculates and displays the representative fraction, putting the denominator on ' the clipboard so it can be pasted into the 034 field if desired. As it is designed to ' be used for scales on maps, the unit of length of the first number is only inches or ' centimeters (i.e., it is not a general-purpose unit converter).
Added on Pi Day. Just was alerted to another tool, Scale Finder.
Scale Finder converts linear scales to representative fractions and vice-versa. It is an invaluable tool for cataloguers and map users and is free to non-commercial users.
