In order to convert 3 feet (3ft) to inches (in) we need to know how many inches are in one foot. This is our conversion factor.:

1 foot = 12 inches

Step 1: Determine the number of feet that you want to convert to inches.

Step 2: Multiply the number of feet by 12. This is because there are 12 inches in one foot.

For our example where we have 3 feet and want to know how many inches this represents:

Step 1: 3 feet
Step 2: 3 ft x 12 in/ft = 36 inches

Note that the unit ft cancels out and we are left with inches as our answer.

Therefore, 3 feet is equal to 36 inches.
