Some SI Derived Quantities Volume Volume is a derived quantity and has the dimensions of length 3 . Thus, the SI unit for volume  is the cubic meter which has the abbreviated symbol m 3 . In practice, the cubic meter is not a  convenient unit for everyday use, so the cubic decimeter (dm 3 ) is used instead. Because it is  so often used 1 dm 3  is given the name  liter . The abbreviated symbol for a liter is L or l. 1 liter = 1 dm 3 When working with even smaller volumes the cubic centimeter is more commonly used.  Since 1 L = 1 dm 3  = (10 cm) (10 cm) (10 cm) = 1000 cm 3 , we often use 1 mL (mL is the symbol for milliliter) in place of 1 cm 3 . You will sometimes see  a mL called acc, which stands for cubic centimeter.

Unformatted text preview: Pressure Pressure is a derived quantity and has the dimensions of mass/(length•time 2 ). The SI unit for pressure is kg/m-s 2 . This product of base units is given the name pascal and the symbol Pa. 1 Pa = 1 kg/m-s 2 Energy Energy is a derived quantity and has the dimensions of mass/(length•time) 2 . The SI unit for energy is kg/m 2-s 2 . This product of base units is given the name joule and the symbol J. 1 J = 1 kg/m 2-s 2 Electric Charge Electric Charge is a derived quantity and has the dimensions of current•time. The SI unit for electric charge is A-s. This product of base units is given the name coulomb and the symbol C. 1 C = 1 A-s...
