Use dimensional analysis to convert the quantity to the indicated units. $12 \mathrm{ft}$ to in. in. (Round to the nearest hundredth as needed.)

Step 1 ：Given that there are 12 inches in a foot, we can convert the given quantity in feet to inches by multiplying it by 12.

Step 2 ：Let's denote the given quantity in feet as 'feet' and the conversion factor as 'inches_per_foot'.

Step 3 ：So, feet = 12 and inches_per_foot = 12.

Step 4 ：By multiplying these two values, we get the equivalent quantity in inches. That is, inches = feet * inches_per_foot = 12 * 12 = 144.

Step 5 ：So, the equivalent of 12 feet in inches is \(\boxed{144}\) inches.
