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 = 109 Hz, 1 km = 103 m, 1 cm = 10−2 m, 1 mA = 10−3 A, 1 nm = 10−9 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]].

== Regents Exam Questions ==
Released Regents questions that cannot be answered without this table, listed by exam. Each link opens the question with its answer key; the standard is the one the question assesses.

''No released question has needed this table yet.''
