More interesting stuff from the NIST fact sheet on FPLA: [begin quote] "Rule of 1000 -- The selected multiple or submultiple prefixes for SI units shall result in numerical values between 1 and 1000. This rule allows centimeters or millimeters to be used where a length declaration is less than 100 centimeters. For example: 500 g not 0.5 kg; 1.96 kg not 1960 g; or 750 mL, not 0.75 L, or 750 mm or 75 cm, not 0.75 m;
Number of Digits -- SI declarations should be shown in three digits except where the quantity is below 100 grams, milliliters, centimeters, square centimeters, or cubic centimeters, where it can be shown in two digits. In either case, any final zero appearing to the right of the decimal point need not be shown."
