From liters per second to volume.
The calculator supports liters, cubic meters, liters per second and cubic meters per hour alongside its US units. Select a compatible answer unit to see the worked conversion.
5 liters per second for 2 minutes
Two minutes is 120 seconds. At a constant or average 5 liters/second, the volume is 5 × 120 = 600 liters, or 0.6 cubic meters.
Liters per second to cubic meters per hour
Multiply by 3,600 seconds/hour and divide by 1,000 liters/cubic meter. Thus 1 liter/second = 3.6 cubic meters/hour. Reverse the conversion by dividing by 3.6.
Connecting to US gallons
The tool uses 3.785411784 liters per US liquid gallon. Ten US liquid gallons is 37.85411784 liters. This is not an Imperial-gallon conversion.
NIST Handbook 130 (2012), printed page 245 lists the gallon/liter relationship. The underlying dimensional conversion is used here for arithmetic, not the handbook’s retail pricing rules. Source checked September 12, 2026.
Watch both the volume and the time unit
Liters/second and cubic meters/hour differ in two dimensions of the written rate. Keep the time conversion visible and round the final answer, rather than rounding every intermediate factor. Four added original drills practice these relationships.
