16 C.F.R. § 500.18

Current through October 31, 2024
Section 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 factor1
Kilo-kx 103
Deca-da* 10
Deci-d* 10-1
Centi-c* 10-2
Milli-m* 10-3
Micro-[MICRO]* 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.
