Final answer:
Fuel flow is commonly measured in liters per minute (L/min), while the official SI unit is cubic meters per second (m³/s).
Step-by-step explanation:
The unit of measure that is generally used to indicate fuel flow is liters per minute (L/min). However, the official SI unit for flow rate is cubic meters per second (m³/s). Given that a liter is defined as 1/1000 of a cubic meter or 1000 cubic centimeters, these units help express the volume of fluid passing through a given point per unit of time. For practical purposes, especially in automotive contexts, liters per minute is a more common unit for measuring fuel flow, as it conveniently represents the volume of fuel an engine consumes per minute.
