Department W had 2400 units, 1/3 completed at the beginning of the period. 16,000 units were transferred to Department X from Department W during the period, and 1800 units were one-half completed at the end of the period. Assume the completion ratios apply to direct materials and conversion costs.

What is the equivalent units of production used to compute unit conversion cost on the cost of production report for Department W (Assuming the company uses FIFO)?
