Measurement units and standards are different in different countries but to maintain a standard, SI units are mostly used when dealing with projects involving different countries or even different states. Small projects can be done with the locally used unit system but when the project is big, one standard unit system is to be used.

Two most common system used in the United States are

United States Customary System (USCS)
System International (SI)

But the SI unit system is more widely used all over the world. Following is the table which shows how you can convert USCS measurements in SI measurements. ( Just multiply the USCS amount with the corresponding figure given in table below

Convert USCS into SI Units

USCS unit X Factor = SI unit SI symbol
Square foot X 0.0929 = Square meter M2
Cubic foot  X 0.2831 = Cubic meter M3
Pound per square inch X 6.894 = Kilopascal KPa
Pound force X 4.448 =  Newton Nu
Foot pound torque X 1.356 = Newton meter N-m
Kip foot X 1.355 = Kilonewton meter LN-m
Gallon per minute X 0.06309 = Liter per second L/s
Kip per square inch X 6.89 = Megapascal MPa
