Pasternack's RF calculators and conversions section provides engineers valuable and easy-to-use tools ranging from complex mathematical formulas to simple conversions. Our RF and microwave calculators and converters will provide the figures you need for your radio frequency engineering needs. RF calculations and RF conversions include metric-standard, link budget, coax cable, power, attenuation, frequency and many more.

**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.

Prefix	Symbol	Value
Tera	'T'	10¹²
Giga	'G'	10⁹
Mega	'M'	10⁶
kilo	'k'	10³

Prefix	Symbol	Value
pico	'p'	10^-12
nano	'n'	10^-9
micro	'u'	10^-6
milli	'm'	10^-3
