ABSTRACT

Of considerable importance in engineering is knowledge of units of engineering quantities, the prefixes used with units, and engineering notation. We need to know, for example, that

80 kN = 80 × 103N which means 80,000 newtons

and 25 mJ = 25 × 10-3J which means 0.025 joules

and 50 nF = 50 × 10-9F which means 0.000000050 farads

This is explained in this chapter.
