Exact Measurement

Think of a measurement of an item, such as volume, distance, length, surface area, or another conceivably measurable aspect of an object that is smaller than Gargantuan. Use the spell on the object, and it will return to you, mentally, the exact measurement of the object up to 100 decimal places. The spell must be used every 500 feet of length an object has to acquire this measurement for the entire object.
