This fence post concrete reference table shows the total concrete volume for a range of hole diameter values, assuming a hole depth of 0.6 m, a post width (square) of 0.1 m and a number of posts of 5. Every figure is computed with the same engine that powers our Fence Post Concrete Calculator, so the numbers are exact.
