Architectural Units – Notation • Most architectural drawings use the architectural representation displaying measurements in feet and inches • Example: 16′-2″ means 16 feet and 2 inches

Unit Conversion

Unit Conversion Desired Unit • feet to inches: 1 ft = 12 in. Given Unit ◦ The ratio of inches to feet is 12: 1 • miles to feet: 1 mi = 5280 ft or ∘ The ratio of feet to miles is 5280: 1

Unit Conversion • Conversion factor – Using a conversion factor to cancel unwanted units is similar to canceling common factors when multiplying fractions

Unit Conversion Example: Convert 17. 2 yards to feet 3 ft = 1 yd

Unit Conversion Your Turn: Convert 4 feet to inches 12 in. = 1 ft

Unit Conversion Example: Convert 2′-5″ to inches 12 in. = 1 ft

Converting to Inches Your Turn 12 • 1 foot = _______inches 12 in. + 8 in. = 20 • 1 foot 8 inches = ______inches • 3'-6″ = ________inches • 15′-11″ = _________inches • 21 ft = ______ yards

More Unit Conversions If 4 Blocks = 1 Inch in length • What is the conversion factor for inches to blocks? Desired Unit Given Unit • How many blocks in 3 inches? 3 inches = ________blocks

More Unit Conversions Your Turn If 4 blocks = 1 Inch in length • 6 in. = _________blocks • 2 ½ in. = _________blocks • 4 ¾ in. = _________blocks

Converting Architectural Units = 7 ft + 0. 333 ft 1 ft. = 12 in. = 7. 333 ft

Converting Architectural Units = 23 ft + 0. 5 ft = 23. 5 ft 1 ft. = 12 in. = 16 ft + 0. 75 ft = 16. 75 ft

Converting Architectural Units What are the dimensions of Bedroom #3? Convert to Decimal Feet 10′- 5″ x 12′- 5″ Calculate the Area of this room 129. 348 sq ft
