Inches, Feet, Yards
How many inches in a foot?
How many feet in a yard?
How many 1/4 inches in an inch?
How many 1/8 inches in an inch?
Can you figure out the pattern?
How many 1/16 inches in an inch?
How many 1/32 inches in an inch?
12 inches (0’-12”)
3 Feet (3’-0”) 4 8 16 32

A = ¼ in.
B = 14/16 = 7/8 in.
C = 1 10/16 or 1 5/8 in.
D = 2 3/16 in.
E = 2 14/16 or 2 7/8 in.
Take this opportunity to discuss reducing fractions.
This is also a good time to reinforce the denominator based on the length of the line.

6. Architectural Units – Notation
Most architectural drawings use the architectural type of scale displaying measurements in feet and inches, such as 16’-2”.

7. Convert These Measurements
1 Foot = _______Inches
1 Foot 8 Inches = ______Inches
3 Feet 6 Inches = ________Inches
If 4 Blocks = 1 Inch in length, then
3 Inches = _________Blocks
2 ½ Inches = _________Blocks
4 ¾ Inches = _________Blocks 12 20 42 12 10 19

8. Converting Architectural Units
Converting units is a valuable skill that will help you solve many problems and avoid lots of mistakes. The process of converting feet-inches to decimal feet is simple and powerful. You will use this method to calculate area and perimeter in future activities.
7’- 4” = 7’ + 4/12” = 7.333’
10’-6” = 10’ + 6/12” = 10.5’

Converting Architectural Units
Students will want to convert 10’-5” to 10.5’. It’s very important to introduce this inconsistency now as we will encounter it throughout the unit.
What are the dimensions of Bedroom #3?
Convert to Decimal Feet
Calculate the Area of this room
10’-5” x 12’-5”
10’+5/12” x 12’+5/12” = ’x12.417’
