To convert flow from L/min to L/s, divide by 60.

The key idea is that there are 60 seconds in a minute, so converting from liters per minute to liters per second uses that 1 minute = 60 seconds. To express a flow rate in L/s when you have L/min, multiply by 1/60, or equivalently divide by 60. So L/s = L/min ÷ 60. For example, 120 L/min becomes 2 L/s (120 ÷ 60 = 2). This is why dividing by 60 is the correct method. Dividing by 30 would imply 30 seconds per minute, dividing by 120 would give an even smaller value, and dividing by 360 would overcorrect; none match the actual 60 seconds per minute.
