Convert volumetric flow rate

Convert liters, cubic meters, US gallons, and cubic feet per unit time. US gallons are explicitly labeled so they are not confused with Imperial gallons.

This page converts volume per time only. Converting to mass flow requires fluid density, which can vary with material, temperature, and pressure.
