If you are comparing two variables using slope, and the resulting ratio has no units of measurement (e.g., $ ext{ft}/ ext{ft}$), what is the standard procedure to express this as a percentage (%)?

Question

Accepted Answer

Multiply the numerical value by 100.. When both rise (vertical change) and run (horizontal distance) are measured in the same units (e. g. , ft/ft), the resulting ratio is unitless. To express this as a percentage ($ ext{\%}$), you must multiply the numerical value by 100, as per standard slope calculation conventions described in the text.
