A cubic mile (abbreviation: cu mi or mi 3 [1]) is an imperial and US customary (non-SI non-metric) unit of volume, used in the United States, Canada and the United Kingdom. It is defined as the volume of a cube with sides of 1 mile (1.6 km ) length, giving a volume of 1 cubic mile (4.2 km 3 ).
Square miles should not be confused with miles square, a square region with each side having a length of the value given. For example, a region which is 20 miles square (20 miles × 20 miles) has an area of 400 sq mi; a rectangle of measuring 10 miles × 40 miles also has an area of 400 sq mi, but is not 20 miles square.
For example, 1 kilometre is 10 3 (one thousand) times the length of 1 metre, but 1 square kilometre is (10 3) 2 (10 6, one million) times the area of 1 square metre, and 1 cubic kilometre is (10 3) 3 (10 9, one billion) cubic metres.
The IEEE symbol for the cubic foot per second is ft 3 /s. [1] The following other abbreviations are also sometimes used: ft 3 /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.
One cubic inch (assuming an international inch) is equal to: 0.000578704 cubic feet (1 cu ft equals 1,728 cu in) Roughly 1 tablespoon (1.0 U.S. gallon = 256 U.S. tablespoons = 231 cubic inches) About 0.576744 imperial fluid ounces; About 0.554113 US fluid ounces; About 0.06926407 American/English cups; About 0.000450581 imperial bushels
The decimetre (SI symbol: dm) is a unit of length in the metric system equal to 10 −1 metres ( 1 / 10 m = 0.1 m). To help compare different orders of magnitude , this section lists lengths between 10 centimeters and 100 centimeters (10 −1 meter and 1 meter).

The square foot (pl. square feet; abbreviated sq ft, sf, or ft 2; also denoted by ' 2 and ⏍) is an imperial unit and U.S. customary unit (non-SI, non-metric) of area, used mainly in the United States, Canada, the United Kingdom, Bangladesh, India, Nepal, Pakistan, Ghana, Liberia, Malaysia, Myanmar, Singapore and Hong Kong.
