Convert 25 yards to inches
using the method of dimensional analysis

Explanation:

25 yard [3 feet / 1 yard] [12 inches / 1 foot] = 25 * 3 * 12 = 900 inches in 25 yards.

Always put the unit you are going to on top and the unit you are coming from on the bottom.

So in this example, you want to going to feet to start with. That's on top. Yards are on the bottom of the first bracket.  In second bracket feet are on the bottom, inches are what you are going to on the top.
