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.
Square footage is measured as length multiplied by width. Thus, a 10' x 12' room would measure 120 square feet (10 x 12 = 120). Then, simply add in the waste factor. Let's say your room requires 120 square feet.If the waste factor is 10%, then you would need 132 square feet.hus, a 10' x 12' room would measure 120 square feet (10 x 12 = 120).
