SI metric prefixes.

§ 500.18 SI metric prefixes. The following chart indicates SI prefixes that may be used on a broad range of consumer commodity labels: Prefix Symbol Multiplying factor  1 Kilo- k x 10 3 Deca- da × 10 Deci- d × 10 −1 Centi- c × 10 −2 Milli- m × 10 −3 Micro- µ × 10 −6 1  10 2 =100; 10 3 =1000; 10 −1 =0.1; 10 −2 =0.01. Thus, 2 kg=2 × 1000 g=2000 g, and 3 cm=3 × 0.01 m=0.03 m.
