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 103 |
| Deca- | da | × 10 |
| Deci- | d | × 10 |
| Centi- | c | × 10 |
| Milli- | m | × 10 |
| Micro- | µ | × 10 |
1 102=100; 103=1000; 10
Thus, 2 kg=2 × 1000 g=2000 g, and 3 cm=3 × 0.01 m=0.03 m.
