Cubic foot
Template:Short description Template:Infobox unit The cubic foot (symbol ft3 or cu ft)<ref name="IEEE">Template:Cite book [1], Template:Isbn, Template:Isbn.</ref> is an imperial and US customary (non-metric) unit of volume, used in the United States and the United Kingdom. It is defined as the volume of a cube with sides of one foot (Template:Val) in length, or exactly Template:Convert, which is very close to Template:Sfrac of a cubic metre).

Template:AnchorCubic foot per second and related flow rates
The IEEE symbol for the cubic foot per second is ft3/s.Template:R The following other abbreviations are also sometimes used:
- ft3/sec
- cu ft/s
- cfs or CFS
- cusec
- second-feet
The flow or discharge of rivers, i.e., the volume of water passing a location per unit of time, is commonly expressed in units of cubic feet per second or cubic metres per second.
Cusec is a unit of flow rate,<ref name="Row">Template:Cite web</ref> used mostly in the United States in the context of water flow, particularly of rivers and canals.
