How do you convert RF to verbal scale?

To convert from RF to Verbal Scale you convert the fractionto familiar units of measurements; for example:

1. 1:250,000.
2. 1 inch = 250,000 inches.
3. 1 inch = 250,000 inches [d] 12 inches/foot = 20,833.3feet.
4. 1 inch = 20,833.3 feet [d] 5280 feet/mile = 4 miles or.
5. 1 inch = 250,000 [d] 63360 inches/mile = 4 miles.
