Water Flow Rate Calculator – Volume & Time (L/min, m³/s)

Calculate water flow rate from volume and time, or find volume/time from flow rate.

Flow Rate: 3.33 L/s (200.00 L/min, 0.00333 m³/s)
Volume: 100.00 L
Time: 30.00 s

Formula: Q = V / t. Common units: L/s, L/min, m³/s, GPM.

Water Flow Rate

Flow rate is the volume of water passing a point per unit time: Q = V / t. Used in plumbing, irrigation, and engineering .
