In accordance with ACI 522R-10, the pervious concrete is designed for 1 cubic yard of concrete. If I were to design the pervious concrete in SI units, should I design for 1 cubic meter or should I take 1 yard = 0.9144 meter? Thanks
You can change the unit into SI directly by converting the unit from yard to meter. But the important part is,if you change the unit for one parameter you have to maintain that for the entire analysis part.
