A tool to convert dbm to milli watts. dBm is defined as power ratio in decibel (dB) referenced to one milliwatt (mW). It is an abbreviation for dB with respect to 1 mW and the "m" in dBm stands for milliwatt.

You provide Outer Diameter (D), Inner Diameter (d), and Permittivity (εr) values then the calculator gives you Zo (ohms), fc Cut off frequency(GHz), C/length (pF/m), and inductance L/length (nH/m). Other tools are available for impedance measurement, dbm to milli watt converter, reflection coefficient calculator, etc.

Tools are provided for measurement of cable impedance, Dual Dielectric Coax Calculator, Milli Watts to dBm Calculator, dBm to Milli Watts Calculator, Reactance Calculator, reflection coefficient Calculator return loss Calculator, and return loss Calculator(by using VSWR) Skin Depth Calculator VSWR Calculator VSWR Calculator(by using RL) Wire Over Ground Calculator
