Sakrete Concrete Calculater
This program is a joke. You would think that a concrete mix material supplier would hire a professional programer to develop a program for them and make sure it it works properly before releasing it. The input screen ask for input in inches (in) which does calculate accurately the cubic yard of concrete or number of bags required. This is a very basic calculation that anyone can do on an ordinary calculator. WxD (ft) x D (in) /12 = cu ft Divide by 9 to get cu yd. Number of bags is determined by dividing the cu yd by 150 (the normal weight of a cu yd of concrete).
