Thank you for the info. Can I check my understanding with you....

If one revolution of the dial is 0.071 ft^3 then 14 revs would be
equivalent to 1 ft^3.

However, it looks as if the red digit is 0.1 ft^3. So wouldn't the red
digit get advanced for every 1.4 revolutions of the dial?

Yes, it should.
