Units in process, May 31.40% complete 30,000 With respect to conversion costs Why: The physical flow schedule traces the units in process regardless of their stage of completion. To calculate equivalent units, weighted average counts prior-period output in BwTP as belonging to the current period. Thus, all completed units are treated as output of the current period. There is no requirement to calculate the work needed to complete the units in BwIP. Once weighted average equivalent units are calculated, the FIFo equivalent units can be obtained by subtracting out the prior-period output found in BwTP.
