The '''Prefixes for Powers of 10''' table from the ''Reference Tables for Physical Science: Physics'' (2025 Edition) gives the ten metric prefixes used on the exam with their symbols and powers of ten. It is needed whenever a quantity in a question is given with a prefix that the equation's units do not use: gigahertz and megahertz frequencies on [[The Electromagnetic Spectrum (Physics)]] and in [[HS-PS4-1]] and [[HS-PS4-5]], nanometer wavelengths, kilometers and centimeters in motion problems, kilowatts and milliamperes in circuits.

== What the prefixes table shows ==
A prefix multiplies the unit it is attached to by the power of ten in the table: 1 GHz = 10<sup>9</sup> Hz, 1 km = 10<sup>3</sup> m, 1 cm = 10<sup>−2</sup> m, 1 mA = 10<sup>−3</sup> A, 1 nm = 10<sup>−9</sup> m. The list is the same as in the 2006 edition of the physics reference tables; the chemistry reference tables keep only [[Selected Metric Prefixes|four of these prefixes]].
