It is the EQUAL flow rate value of 1 cubic meter per second but in the Liters per second flow rate unit alternative. CONVERT : between other flow rate measuring units - complete list. 4 takeaways from the most juvenile debate in history. The link to this tool will appear as: flow rate from cubic meter per second (m3/sec) to Liters per second (L/sec) conversion. Calculate from flow rate into other flow rate unit measures. The other way around, how many Liters per second - L/sec are in one cubic meter per second - m3/sec unit?
