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.
To find the square footage, multiply the width (in feet) by the length (in feet.) For example, if you need to find the square footage of a room that is 7 feet long and 10 feet wide, you would perform the following calculation: 7â x 10â = 70 square feet.
