The following chart indicates SI prefixes that may be used on a broad range of consumer commodity labels:

PrefixSymbolMultiplying factor 1
Kilo-kx 103
Deca-da× 10
Deci-d× 10−1
Centi-c× 10−2
Milli-m× 10−3
Micro-µ× 10−6
1 102=100; 103=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.
