The following characteristics of coffee have an adverse effect on the upper GI tract: Coffee Decreases Pressure in the Lower Esophageal Sphincter Coffee has been shown to decrease pressure in the lower esophageal sphincter, contributing to gastroesophageal reflux.
Here is how to properly measure and calculate total square footage of the space. 1  Split the room into separate areas. 2  Measure each area of the room separately (area 1, area 2, area 3). 3  Calculate the square footage of the each space by multiplying length by width. 4  Room: Length (ft) x Width (ft) = Square Footage.
Step 1. Find the amount of square feet in a room or given area by multiplying the length by the width. So if the width is 10 feet and the length is 10 feet, your area is 100 square feet. Step 2. Determine the square root of the footage if you do not know what the length and width are.
