**Note: All of our radio frequency calculators allow SI prefix input. For example, if you wish to input"25000000", just type "25M" instead. Keep in mind that some calculators for RF have hard-coded units; if the label says (nF), for example, there is no need to input "10n", as your input is already considered to be in nanofarads. See the quick-reference table below for all compatible SI prefixes.
