Liter

Definition

A liter is a metric unit of volume equal to 1,000 cubic centimeters (cm³) or 1,000 milliliters (mL). It is commonly used to measure fluid quantities.

Flow Rate: The quantity of fluid passing through a point per unit time, often measured in liters per second (L/s) or cubic meters per second ($$m^3/s$$).

Velocity:

The speed at which fluid particles move in a specific direction, typically measured in meters per second (m/s).

Cubic Meter: A unit of volume in the International System of Units (SI), equal to the volume of a cube with edges one meter long ($$1 m^3 = 1,000 L$$).
