How to Measure Concrete to Be Poured: 10 Steps (with Pictures)

May 24, 2020 · If you're calculating for cubic feet or cubic yards of concrete needed, you will need to convert your inch measurements to Engineers Scale. Engineers scale is basically taking a foot (12 inches) and converting it into10ths. The engineers scale also eliminates the fractions of an inch. (i.e. 3/4 of an inch is equal to 0.75 of an inch)
