The unit SQ.IN denotes what?

• A. SQ.CM
• B. SQ.FT
• C. SQ.MM
• D. SQ.IN

Answer: (D)

SQ.IN denotes square inches, an area unit in the imperial system. The prefix “SQ” shows we’re talking about area (not a length), and “IN” is short for inches. So it represents the area of a region measured in inches by inches—a one-inch by one-inch square is one square inch. For context, other square units like square centimeters, square feet, or square millimeters measure the same kind of quantity in different unit systems, with conversions such as 1 square foot = 144 square inches and 1 square inch ≈ 6.4516 square centimeters.
