USCS - United States Customary System Units - the measuring units used in the U.S. is based on the

• mile
• foot
• inch
• gallon
• second
• pound

USCS units are also called the Imperial units. Imperial or USCS units are gradually being replaced by SI units.

Commonly used USCS and SI-units

USCS unit	SI unit	SI symbol	Conversion factor (mutiply USCS unit with factor )
Square foot	Square meter	m2	0.0929
Cubic foot	Cubic meter	m3	0.2831
Pound per square inch	Kilopascal	kPa	6.894
Pound force	Newton	N	4.448
Foot pound torque	Newton meter	N·m	1.356
Kip foot	Kilonewton meter	kN·m	1.356
Gallon per minute	Liter per second	L/s	0.06309
Kip per square inch	Megapascal	MPa	6.89

•   a kip is 1000 lb

More conversions:

• Convert from USCS or Imperial Units to SI Units
• Metre is the British, SI and elsewhere spelling of the unit of length equal to 100 cm. Meter is the American spelling of the same unit.
