SI UNIT PREFIXES SELECTED RULES FOR WRITING METRIC QUANTITIES Multiplication Factor Prefix Symbol l. (a) Use prefixes to keep numerical values generally between 0.1 and 1.000. I 000 000 000 000 : 10l2 terra T (b) Use of the prefixes hecto, deeka, deci, and centi should be generally avoided 1 000 000 000 : 109 giga G except for certain areas or volumes where the numbers would be otherwise I 000 000 : 106 mega M awkward. 1 000 : 103 kilo k (c) Use prefixes only in the numerator of unit combinations. The one exception 100 = 102 heoto h is the base unit kilogram. (Example: write kN/m not N/mm; J/kg not mJ/g) 10 : 10 deka da ((1) Avoid double prefixes.

Unit designations _ 0.0] : 10"2 centi c (a) Use a dot for multiplication of units, (Example: write N'm not Nm) 0.001 : 10“3 milli m (b) Avoid ambiguous double solidus.
