But this has been exacerbated by human activities which have led to: 1) an increase in greenhouse gas emissions that causes heat to remain trapped within the troposphere, and 2) a decrease in ozone in the stratosphere, causing less sunlight to be absorbed by the ozone layer, resulting in a cooling of the stratosphere.
When measuring for floor tile the rule is: Length x Width + Waste = Amount Needed. Waste Factor will vary based upon tile size, layout, configuration of room, patterns, etc. Typical waste factor is about 10%. Add 15% for tile being installed diagonally or for a room with lots of jogs and corners.
Measure the square footage of the room or area (multiply the length times the width), enter it in the calculator, press âCalculateâ. Example: Bedroom: 15 feet by 10 feet. Multiply 15 by 10 to get 150 square feet. Enter 150 into the calculator, press âCalculateâ and you get your answer: 16.67 square yards. Take that with you to the store to make shopping for tile or carpet that much easier. 1 square foot equals 0.1111 square yards. 1 square yard equals 9 square feet. 1 square yard equals 1,296 square inches.
